Last 3 months my periods have been regular with 31 days interval. We have been doing follicular study for last 2 months to see if and when rupture happens. Rupture took place on 13th day after periods. We kept relations 5 days prior the predicted rupture date and also after that to make sure before and after ovulation there is maximum chance of pregnancy. Last month I had all symptoms of pregnancy but periods took place after 31 days. This is the 2nd month we are trying the same cycle, feeling mild cramps, eagerly waiting to know if implantation will happen or not. Today is the 24th day after periods, but no signs of implantation like bleeding.
