A quick rundown so I can give all the information I can think of... I had been on birth control for a year, July was my last month on it. In August I had unprotected sex, he was afraid he didn't pull out in time so to be safe I took Plan B (not quite 2 days after intercourse) and had a normal period. I counted to see when my approx. start date would be this month (before birth control I was always 1-10 late). It would've been the 26th. On the 21st I had sex. It is now the 29th, my period is not here. I'm having pink spotting that started yesterday. Now I'm freaking out. I'm not sure if I'm pregnant or if my body just hasn't had time to get back on a regular cycle. Any insight would be greatly appreciated. Please and thank you.
