I got my period Dec 23 - Dec 27 and I suddenly got it again. I think it’s my period but I did have sex on the 28th, they day after it ended. The guy I had sex with did go a little overboard during sex so maybe that’s why it came early. My cramps seem regular and I should have a heavy flow but it’s like I’m spotting and I’m stressing way too much. Maybe it’s my mind playing tricks on me but could I be pregnant and should I be worried?
