I had my last period on 22nd August 2012 which lasted until 28th of that month. However, I was on the pill and when I stopped this period occurred. My normal period was on the 3rd of August and ended on 8th. I had started taking the pill on 3rd but stopped on the 18th without completing the 21 day cycle because I was having some unpleasant spotting during ovulation , so I consulted a GP and she said I could stop taking it straight away. As soon as the second period ended in August on 28th, I had protected sex (my partner used a condom). I was supposed to have got my period around the 20th or 22nd of September, but it still hasn t shown up. What are the chances of me being pregnant? My periods follow a normal cycle between 25 and 28 days usually and this is the first time since I had been diagnosed with PCOS that the irregularity occurred. I also have been having some PMS-related stomach cramps since 18th September, which I usually get when I am about the start my period or when menstruating. Is it likely that I am pregnant? In order to deal with the PMS issues, I asked my doctor to prescribe medication , and she gave me Duphaston and asked to take it from 23rd to 27th September and 4-5 days after that I should get my period. Is there anything I need to worry about?
