Hi All, I got my HCG injection of 5000 unit on Day 17 ,when my follicle size was 20mm. Following that I started progesterone tablet for 10 days. I was in relationship with my husband on the day of HCG shot and one day after that, as doctor suggested. All my test and husband's test were normal. I had high BP for which dr gave me labebet 200mg  3 times a day. I am from obese category. Dr was pretty confident that i will get pregnant this time. But 2 days after stopping progesterone i got my periods. I am sad and confuse as to why we missed it. Can you please let us know what can be the possible causes?
