I have been on cerazette for 7 months and don't get any periods at all. In the pas if I have missed a pill I have slight spotting for a day or two. However the past few weeks have been stressful and I have missed 8 pills. The dates are as follows for missed pills; Thursday 11th Saturday 13th (if memory serves me correctly I had sex over this weekend) Friday 19th Sunday 21st Tuesday 23rd Thursday 25th Friday 26th Saturday 27th. My period usually came around the 20th of the month before I went on the pill. My question is without having periods now what are my chances of being pregnant and how would I know, would I have symptoms already or when would they start? Thank you
