I started birth control 6 months ago but switched to a new one 3 months ago. Last month I was not very good with my pills and missed 3 in a row so i just stopped taking them till i got my period and started up the next pack on the next sunday. This month I still have not gotten my period and am on the 4th day of sugar pills. I do not even have any signs showing that its coming (cramps, bloating, etc) should I be worried of pregnancy or is it possible that my cycle is messed up because what I did the month before? When me and my boyfriend do have sex he pulls out before even on birth control I'm not sure if that is even helpful but I am pretty worried and would like any advice that can possibly be given.
