I had sex on the 21 of December with someone else and the condom broke. My period came on on the 15 and went off on the 19. I took the plan b pill an hour after sex. I'm now bleeding on the 26. Does that mean the plan b pill worked? I must add that I'm ttc with my bf, and I know this slip up has messed up me ttc for this month. When would I be able to conceive with my bf? What does the bleeding mean?
