I had sex with my boyfriend on the 26th of aug, 2017. He had a condom on and he did not ejaculate inside the condom too. On the 1st of September I got my regular period. It’s 30th of Oct now and I still haven’t gotten my period. I took a test on the 23rd of oct and it came out negative. It’s been two months now since my delayed period. I’m worried. Please help. I’ve gained a lot of weight too in these two months so I’m assuming my period is delayed because of that.
