very slim, but it has happened , if u have stopped birth control to become pregnant good luck with it , it took me nearly 2 years to fall after i stopped takeing the pill but hey every1 is different , i would wait and see if you have yr next period if not take a test but like i say if you stop yr birth control that could also mix up your cycle too xx
I had been on the patch for almost 3 years and my husband and I decided we wanted to try for a baby. I took my patch off in july and had a period immediately. The next month I didn't have a period and took a pregnancy test and the result was negative. The next month I skipped a period again and discovered I was pregnant, so I didn't even have a period and still got pregnant. I would say it can happen.
