Had unprotected sex with my BF I haven’t got my period in 7 days now. I used to be on B/C I didn’t have a period for four years, I’ve been off of it for four-ish months, and I’ve had my period after the hole time. I don’t know If that effects anything or not. But my boobs hurt, they’re swollen. I’m very emotional, I cry over just about anything. And moody! I took a test when I was 4 days late. It showed negative. Should I take another?
