I know that you guys hate these kinds of questions but here goes..

As some of you know I just had my son on september 28th. 5 weeks after he was born I started having sex again, some protected but mostly unprotected. I stopped exclusively breastfeeding about a month and a half ago, now I only do it once a day...If that. I have birth control pills that I got on november 9th-or10th,but the doctor said that when I stop breastfeeding immediately schedule a appointment to get regular birth control pills.Another thing is that with these pills is that the day I got them I lost the pack, it was a 28 day pack. I havent told anybody to avoid the critisism. I know some of you might talk about me but we did not want another baby. But I have been having these mild cramps like my period is coming for about a week now. The same as when I was pregnant with my son. What are the chances of me being pregnant? Should my period have come? Has this happened to anyone before?

Thanks for the help
