I never really track my period (although I should and I used to I just never got around to doing it after I switched phones and I lost my app data and stuff yea yea yea) but I'm pretty sure I get it around the end of the month.. About a week ago my boyfriend and I had sex (protected) and he came on me then later I washed off in the shower (before he was also on top of me naked aka penis everywhere n yea you can guess) 

Lately I've been kind of crampy but more like mild sharp pains that last for a few minutes, getting that feeling you get sometimes down there you know when you're on my period and also my breasts are just a little tender. I never really get period symptoms before I actually get my period so that's why I'm kind of confused??? I don't really thinnnnk I'm pregnant I'm just like what is my body doing haha
