I'm 25, and have been on sprintec since February. I have never missed a pill until the friday before my period, I had lost it somehow. The following wednesday I started my period, it lasted for 2 days then stopped for 2 days then spotted for a day (not normal in all the years that I have had a period). I went to start my new pack of pills on that Sunday, and I saw that I had thrown the good pack of pills away and only had the non hormone pills from the last pack on my counter. It was Tuesday until I was able to get my new rx filled. I took 2 on tuesday, and 2 on wednesday. I have been sexually active within the last 2 week and the last several days. Are the chances pretty slim that I would become pregnant?
