i took two pills late about a week and a half ago. i usually take my pill in the morning, but i ended up taking the first late one in the evening, about 9 hours late. i was supposed to take the next pill at the right time, but i forgot again and took it in the evening. i have taken every other pill on time since. i had sex today and started to get a little worried. i only have 3 more pills until my white ones, and my pamphlet says that i should be ok after 7 days of missing one. is it likely that i could get pregnant?
