My periods have been delayed by 10 days. I had sex on 25th March which was my fertile day. I did a
pregnancy test on 1st day of missed period and another after 5 days with negetive result in both.
September'17 I had a similar issue and was diagnosed with 1 cystic ovary. I was prescribed Primolut for 7 days after which I had my periods and have been regular till April'18.
My BP is always low around - 90-100/60-70. I also have hot flashes sometimes. I guess I'm also stressed a little for my job.
