I am on the combination pill (Lutera) and took the Tuesday pill of the first week less than 10 hours late. I'm saying 10 to be safe but it was about 7. I usually take my pill at 12 am but I took it at 7 am and had sex around 5 am (in between). I took it after and took the next pill at my regular time. What are the chances I'm pregnant since it was the first week of a new pack.
