My boyfriend and I had sex for the first time about three and a half weeks ago. I was on the last day of my period [minimal spotting] and was on the last of my white spacer pills [I've been on the pill since June of last year]. We used a condom both times.
It's the second day of my white spacer pills this time, and I am worried that maybe some freak incident happened and I could be pregnant. I know that I am probably paranoid, but this is my first time dealing with all of this. What are the chances that pregnancy could occur with the pill, condoms, and the very last day of a period all in one?
