I know I'm not pregnant but I need help to stop stressing???

Caroline

Eyyy so I'm really late on my period and I was wondering what are some other reason I might be late??

I'm dating a girl. But before we started dating I hooked up with an old boyfriend and we didn't have sex, it was just hand stuff. But you know, stuff can happen??

But I also have a lot of stress going on. I just started college and I'm around other girls with other cycles all the time. What are some reasons I'm late??
