So my period is a mess, on de calendar it's supposed to start in 4 days (the app never get it right the day). Two days ago I've had a weird ass cramp that went all the way to my back, yesterday I thought my red friend had come, but it was a white thing (no smell). From that day on I'm ALWAYS hungry, my boobs, omg, hurt so bad and the nipples are weird and hurt, they fell heavy!! Me and my bf had sex with no protection, what are the odds of me being pregnant?!? Does anybody fells like that on their pms??
