I took Plan B around 1/31 and I started bleeding on 2/7 which fell on my period date. I'm not sure if it was a period or side effect bcuz I bled twice the last time I took the pill. And now I'm starting to feel weird. I don't really want to eat anything. Kind of bloating. I slept 10 hours and still feel sleepy. Is it possible that I'm already pregnant when I took the pill but I didn't know? I've had unprotected sex during Jan. And we've been using condom since the accident. I'm very confused.
