Period?

Angelica
So I had unprotected sex. And within three hours I took an emergency contraception pill, although I took the pill I knew that my chances of becoming pregnant are still there. Two weeks later I started on birth control. Weeks later and even now, I've been having these pregnancy like symptoms that are similar to side effects of the morning after pill and the birth control. I know that those pills mess up your body. So I'm confused. Plus, I had a period. Or I think it was a period. It started light like spotting but it got heavier and it stopped edventually, but I keep having light spotting. Could I be pregnant? Or if this a side effect of the morning after pill and birth control? I'm lost and confused and I'm scared. Has anyone else gone through this experience while using birth control?
