I wish my period would start already!

I'm supposed to start today & I know sometimes periods are late, specially if you're under stress or what not (which I gues I am) & I hate when people wonder if they're pregnant when they had unprotected sex, like umm the chances are kinda high, well I had 33% chance of pregnancy the other day & I wanted to have sex so bad & I did, couple days later I'm wondering where my period is at!?😂 I'm in such a weird mood, I want to run away, I feel so trapped here, I want to be who I'm meant to be, I want to take classes I love and meet fascinating people but instead I'm stuck in a room most of the day & my SO tries to be so supportive & wipes all my tears I've been having lately but like I don't want to be understood or held right now, I want to go away from people and be my own person. Ugh sorry about ranting!
