I had unprotected sex with my bf on 26th & 27th of october..He was cum inside me, within this time, I count it is my ovulation day..After having intercourse with him on 27th, I took 1 box of Postinor-2 in the evening. I followed as the direction in the box..that evening i took 1 pill around 7.00pm then the other pill i took on the next day morning..I'm so scared to get pregnant then I took 1 pill again on evening 28th..the remaining pill I didn't take it because while take this pill I'm having a headache,nausea and body weakness.So I stop n skip it..the problem is yesterday while i urinated, i saw some blood in my urine..guess its not from my urine but its from my vagina..Is it the side effect for me because skip the remaining pill??...I'm so scared n worry, pls help me n answer me asap!
