On the 15th day of my january cycle,i had unprotected sex and took p2 and my periods came on the 27th day which was the right day. On my feb cycle i had sex on the 9th day and suspected the condom was broken so i freaked out n took p2 and my periods came on the 20th day which was earlier than 7days.except from those two instances,i havent taken p2 since 2014. Now we decided to conceive and we've been having unprotected sex since the last day of my irregular period. today is cycle day 16 am feeling sort of cramps and i have a pimple that comes wen am a few days to periods. Could it be that the p2 is still working or what could be the problem?
