(You are half galra, and in the pack of ulaz, kolivan, antok, thace. You are also a kit by galra standards even though you are 16. Your a girl so after a few mounths of it being delayed by gravitational shift your period started when the pack was sleeping in the nest. They were shocked that they’re kit was bleeding since galra have both female and male parts and apparently don’t have periods. So when they wake up to you being surrounded by blood they thought you were injured. Galras love kits)
