I had my daughter 8 weeks ago, then on New Years had unprotected sex. I got the Plan B the following morning took the first pill but forgot to take the 2nd pill until 2 days later instead of 12 hours after the 1st pill. I know I'm more fertile now then I'll ever be, is Plan B as effective right after having a baby and if you forget to take the 2nd pill within 12hrs of the 1st pill? I was supposed to start my period on the 5th of Jan 2013 and still haven't started and it's the 9th
