I have been taking Sprintec .250mg/35mg for about 6 years now. I had a miscarriage about 3 years ago on this pill after forgetting to take it for a couple days. I learned my lesson and take it at the specific time of day every single day. My boyfriend and I relay specifically on the pill to prevent pregnancy. Well, the week of my period comes, and low and behold, it arrives a week late, and it was extremely light and lasted for about 2 days. Is there any chance, considering my boyfriend and I put all faith in the pill alone, that I may be pregnant? Before when I was it was different because I miscarried right away.
