Hi, i started taking clomid last month and had blood tests on day 21 of my cycle. They are testing you for progesterone hormone levels which will determine if you have ovulated or not. I was told by my gynecologist that if the levels are above 30 then you've ovulated. If not, your doctor may want to increase the levels of clomid you are taking. This may be what they wish to discuss with you but either way I wouldn't worry.
Thank you for commenting... what happens if I think I ovulated later will day 21 test still show I ovulated? X
I dont believe so, the hormone levels will only determine if you have ovulated before the blood tests. I read somewhere that if you are taking clomid typically you ovulate 7-10 days after taking the last tablet. I would speak to your gynecologist, if you think you have ovulated after day 21 they may do another blood test
