I by accident missed a pill which I never do but I did then the next night wasn't thinking and took the pill for the night before which was Fri. So I woke up Sunday morning realizing that I missed a pill Friday night took one Sat night and then took another Sun morning and got back on schedule Sun night. Does that mean I missed two pills because of the time frame. Do I need to use a back up method of birth control. I am on the pill Called Lolo week 3.
