Hi!! i am having my period irregularly before like longer time was 7 months. I started to take pills (marvelone) and my period came on time for the first month of taking pills. I have finished my 21 tablets of the next month which was from 02.04.2012 and i finished it on 22.04.2012. I wanted to delay my period so i took primolut N from 25 to 27 once a day. I had sex on 27 which prior to the intercourse i have taken 1 pill and after 9 hours i have taken 1 pill again. But i am getting afraid because after finishing the 21 pills i supposed to have my period from 23 to 29 and until now i still do not have my period. So is taking primolut N delayed my period or is there any possibilities of getting pregnant since we do not use condom and it was all inside withdrawn. Please help me on my confusions.
