Hey so this is kinda weird but I don't know what else to do so I'm just going to get to it. I was supposed to start my period on the 18th but didn't, I messed around with my boyfriend (didn't have sex) on the 20th. Kinda started my period the next day but it was just like light brown then the next day it stopped. also, the inside of my vagina is all swollen (i was thinking maybe from the fingering). What does this mean. I don't want to be pregnant obviously, so a little help would be greatly appreciated.
