Hi, i'm on Cilest and missed the first five pills in a row due to the chemist not having them in. I did have unprotected sex with my boyfriend. I assumed (stupidly) the first ones wouldn't matter so much but was then told by a friend they're important to take as i would have in total gone 12 days without having any. I did an online ovulation calculator to try and put my mind at rest and turns out i would have been ovulating on a couple of the days i missed. Iv now started bleeding and have pains in my lower back and abdomen. Is this because iv messed my pills up or could i be pregnant?
The dates if it helps are -
1st Sep - first day of last period finished 5th Sep
7th Sep - Was supposed to start taking pill again
Missed 7th,8th,9th,10th & 11th Sep
Have started bleeding and getting cramps 20th Sep
