I have last mens on 25 March and did hsg on 8th day which comes out to be normal. My next mens should come on 24 April. But neither men's nor positive pregnancy. Few days after ovulation i have some symptoms like no possible to bent, sit etc , pain in lower abdomen etc , even on 14 dpo temp went 98.5 and that night extreme headache . but NXT day everything becomes normal. Test is also negative neither periods came. Since last 5 days  minute headache is also there. Can you help if pregnancy is not there it's ok why mens also delayed
