I have pcod. M taking metmorfin 500 mg 2 times a day and krimson 35. The day before yesterday my 21 day pill pack ended and yesterday my partner rubbed his unprotected penis on my butt. Is their any possibility if he didn't ejaculate to get pregnant? Is it possible if there was sperm in precum (though he went for toilet many times before the act) to flow inside vagina and m on pill and still can get pregnant? I was taking krimson 35 from november and I generally got my menses on the third day after stopping the pill for the month of nov. But today is the fourth day and I still haven't got any menses. I had cetrizine along with krimson as well as my skin treatment is going on (tab minoz er 65 & patadin) will these medicine reduce the effectiveness of krimson? Do I need to worry at all?
