What is the cause of my late period?!? Ive been so so so stressed Basically I had my period around 5th/6th July. I had sex, with a condom, on the 31st July. That was the first ever time I had sex by the way. The condom didnt split, no spillage nothing. It was perfectly intact the whole time. Being a person who just lost their virginity i had paranoia of being pregnant. So i took Levonelle on the 3rd August which was around 68 hours after sex. I was also expecting my period couple days after but it did not come. Being that my last period started around 5th/6th July, my August period is late. It is now 8th August and my period is late. Ive taken a pregnancy test, yes i know its early however it was negative. I just want to know what the cause of my late period is. Is it pregnancy? Levonelle? Stress? What! Ive been so stressed about it. My period has been late for a few days now
