I started my period on the 28th of February. I had sex on the 7th and 8th and didn t use a condom. I took plan b about 40 hours after the first time I had sex. I am on birth control but I forgot to take the last two active pills in the third week and then just started my pills on the usual day. On the 21st we had sex again this time with a condom. afterward I had a little bit of pink discharge. now I am supposed to start my period today and I had some red blood but it was light. my question is whether there is a chance im pregnant?
