(Y/n) knew it had to happen sometime, and it usually happened during the worst moment, but it had to happen anyway; one morning after waking up from a cramping sensation in her lower abdomen (Y/n) realized that she had gotten her period. She thankfully caught it in time and she only got blood on the crotch of her panties, but as soon as she made it to the bathroom she remembered that she didn't have any pads/tampons. By then she knew galra women didn't bleed every month which meant there were no period products, so she had to improvise by making a makeshift pad with the absorbent alien toilet paper; it was soft enough, thankfully, but she didn't know how well it would hold up or how long it would last. (Y/n) already knew what the bottle of liquid painkiller looked like in her medicine cabinet and thankfully Haggar already told her how much to take weeks ago when she first arrived, that way she at least wouldn't have to deal with as much pain. Her mood swings and intense cravings for sweet/salty/spicy foods, along with her other usual pms/pmdd symptoms should have been a warning, unfortunately she had almost completely ignored them.

After making a pad and taking the right amount of liquid painkiller (Y/n) decided to go back to bed, wincing with each step she took; galra aspirin worked better than the kinds that her old reality had, although it still took a while to take effect. She felt a little better once she laid curled up under the blankets on her bed, but she felt emotional and wished that she could cuddle with Sendak. In the meantime, everyone had gathered for breakfast in the dining room; (Y/n) hadn't joined them by the time the servants brought the food to the table, causing everyone present to wonder where she could be. Sendak was the most concerned out of all of them, worried that something happened to (Y/n) which prevented her from coming to breakfast. Sure, he'd noticed the change in (Y/n's) behavior and natural scent within the previous few days, and he wished that he knew more about human behavior and biology.

"Perhaps you should check on (Y/n) to see if she's alright." Zarkon suggested while talking to Sendak, prompting the furry male to go see if she was okay.

"I was thinking the same thing. I'll be back soon." Sendak replied as he stood up, promptly walking out of the dining room.

Everyone sitting at the table watched as Sendak rushed out of the dining room, hoping their human guest was okay. Lotor asked his father about (Y/n's) well-being, but unfortunately not even Zarkon knew the answer and assured his son that she hopefully would be. Sendak was the most worried out of all of them; (Y/n) was never late for a meal which obviously meant something wasn't right and she needed his help. As soon as he arrived at her bedroom he knocked on the door a couple of times, waiting for a response instead of just rudely barging in. When (Y/n) heard a knock on her bedroom door she gave whoever was knocking permission to come in, not at all surprised to see Sendak; she felt happy to see the man she was crushing on, and if she wasn't on her period she would have been excited.

"Are you feeling alright, (Y/n)? When you didn't come to breakfast we were all worr- Why do you smell like you're bleeding?!" Sendak began to say when he first entered her room and walked towards the bed; he thought she was only sleeping in until he smelled blood, immediately rushing to her bedside whilst fearing the worst.

"I'm fine, I just got my period. Please don't worry about me, I'll live." (Y/n) answered with a weak tone, peeking out from under the blanket so she could see him.

"You're on your what? And what does that have to do with the blood scent I smell coming from you?" Sendak asked her in confusion, not quite understanding why she was acting strange and smelled like blood; he was silently panicking, but he decided to listen to her explanation before reacting.

(Y/n) blushed at the thought of telling Sendak about her period and why she had it but she did so anyway, starting with the basics in hopes of not having to explain it in detail. Unfortunately luck wasn't on her side and she had to go into detail about why she was bleeding and how long it would last, feeling incredibly embarrassed from some of Sendak's questions. Sendak was horrified after (Y/n) told him what human women had to go through every month when their bodies matured and they didn't get pregnant; he was astounded that human women could bleed from their uterus for about a week and not die. He felt a little sick as he let the new information set in, hardly able to believe what his crush had to experience every month until she was old. After (Y/n) finished explaining everything she waited for Sendak's response, hoping he wouldn't panic given the horrified expression on his face.

"Is there anything you need that I can get for you?" Sendak questioned as calmly as he could after he came to terms with (Y/n) bleeding, hoping he could help her feel more comfortable during her monthly condition.

"Could you possibly bring me a cup of water and something sweet/salty/spicy to eat?" (Y/n) hesitantly asked him, not wanting him to go out of his way just to help her while wasting valuable time in the process.

"I'll return soon." Sendak replied before he stood up and briskly walked out of her room, ready to get the things she needed as soon as possible.

(Y/n) watched Sendak leave her room and felt a wave of sadness wash through her; she knew he would come back but watching him temporarily leave made her cry. And she let herself cry, but only once she was absolutely sure Sendak was gone because she didn't want him to see her crying during her most vulnerable time of the month. In the meantime Sendak went to go get (Y/n) the items she requested while also making a couple of stops along the way; he went to the infirmary where he informed Haggar of (Y/n's) condition and what she told him it entailed, then he went to the palace seamstress and requested that she make a few pairs of period underwear for (Y/n), that way she wouldn't have to worry about making pads out of toilet paper. He wanted to help the young human woman as much as he could when she was most vulnerable, although he knew that desire was just his instincts kicking in. Sendak also informed Zarkon about what (Y/n) was going through and Zarkon gave him the week off of his duties and training, so he could take care of her until she felt better.

On the way back to (Y/n's) bedroom Sendak couldn't stop thinking about what she had to go through every month until she was past her childbearing years; as soon as he smelled blood coming from her he honestly thought she was dying or someone tried killing her, never once did it occur to him that humans had different reproductive cycles, particularly human women. He already respected (Y/n) before he knew about menstruation, although he thought she was resilient in order to bleed for several days every month the way she did. Having a period didn't sound easy, which was why he wanted to take care of her until her period was done; Sendak didn't want her going through it alone because he cared about her well-being. Once he made it to his destination he quietly knocked a few times and listened for a response, opening the door and walking in after he heard (Y/n) invite him in. (Y/n) wiped her face off before Sendak came into her room, trying her best not to start crying again when she saw him come in.

"I brought you the food and water you wanted, and the palace seamstress is making a special kind of underclothing to help absorb your blood." Sendak quietly informed (Y/n) when he sat on the edge of the bed and put the cup of water and bowl/plate of the sweet/salty/spicy food she wanted on the nightstand.

"Thank you… Sendak, c-can you do one more thing for me?" (Y/n) thanked him for bringing her something to eat and drink; she also wanted to cuddle with him but she was almost too nervous to ask such a thing.

"What is it you need me to do, ange- (Y/n)?" Sendak began to ask her before he cut himself off and corrected himself, feeling embarrassed by the cute nickname he was about to call her.

"I- I want to cuddle with you, and you can call me angel if you want to. I don't mind." (Y/n) shyly responded; she blamed it on her hormones, but she thought it was cute how Sendak called her angel.

Sendak felt a little flustered, although he tried not to let it show while he removed his boots and laid on the bed with (Y/n) who let him under the covers. He moved slowly and gently so that he didn't make her pain worse; from what she told him earlier she would be in pain for the first day or so of her period and the last thing he wanted was for her cramps to be worse. The scent of blood smelled more potent underneath the soft blanket and it overwhelmed Sendak's protective instincts but he had to remind himself that what she was going through was perfectly natural for human women. (Y/n) couldn't believe that Sendak was actually cuddling with her; he felt so warm and he had a certain scent that she couldn't remember the name of, but liked. She just barely held back a sniffle as she started to cry again, feeling even more emotional than earlier.

"What's wrong, angel? Are you alright?" Sendak questioned with a soft tone; he wasn't expecting her to start crying and he started purring whilst spooning her.

"I'm sorry, it's just my hormones." (Y/n) apologized with a sniffle, feeling embarrassed about crying in front of her crush of whom she felt even more in love with during that particular moment.

Sendak purred in response and gently nuzzled the back of (Y/n's) head, trying to comfort her as much as possible even though he knew she wasn't sad about anything. He intended to stay cuddled up with (Y/n) for as long as he needed to; he loved snuggling with her more than he thought he would. (Y/n) felt an array of emotions when Sendak began spooning her from behind; her body felt hot, although she also felt a little shy, somewhat horny and kind of loved. She fell asleep after a few moments and began daydreaming about them being in a relationship with him; she knew he probably didn't like her in a romantic way but she was at least allowed to dream about such a thing. However, little did she know was that Sendak did like her in a romantic way and was just getting to know her better, that way he could eventually court her.
