I got my first shot on February 8th before I started my period. I should have had my period between the 12-13th, but I still haven't started. Is this normal?
Also, I had sex with my boyfriend on the 15th (today) since we weren't able to do it on Valentine's day. We used a condom but it was starting to slip off. My boyfriend noticed and he fixed it but I'm a little worried some of his cum might have gone inside me. Should I take the plan b pill just in case? I'm not sure when the shot should be working.
