I have been on Lutera for a good 2 1/2-3 years now and decided to have unprotected sex. I am sexually active and have always used both pill and condoms but my bf and I decided to not use them for the first time... on top of that there was one day of this month where I took the pill 3 hours late(but i always take it the same time and that's 11 am). Are there any chances of me becoming pregnant?
