Hi every1. I had a period 2wks ago lasting 1wk. I had unprotected sex with my BF 3x last week. Now im having some light bleeding. The first day i had to toss my undies i was bleeding and i didnt know. The second day i had a small show of clots when i wiped. Last night and today there was just a streak of pink when i wiped. The bleeding stopped completely leaving a little pink here and there. Along with this, i have been feeling depressed and constantly crying and having mood swings. Is this a sign of pregnancy? Please help.
