Does ovulation varies in every cycle? I'm on duphaston for the last 8 months . Usually it was 28 day cycle.. but from last 3 to 4 months it was 32 then again back to 28 that way.. and last month it was 34 day cycle.. so I'm really getting confused with ovulation time. This month I have taken letroz 2.5mg. today is 12th day and my
LH urine ovulation test is negative. So is that mean ovulation dint occur yet?
