I had my period Oct. 22-25 and had sex Nov. 2 and took Plan B that exact same day. My cycles are usually regular, 28 days. I bled for about 3 days five days after taking Plan B. Now it's two weeks later and I haven't gotten my normal expected period. I am 3 days late. Also on Nov 21 my fiancé came in me and I didn't take plan b. He came in me last night as well and haven't taken plan b. Is there a chance I could get pregnant? I'm not sure if I've ovulated since the plan b messed up my cycle.
