Okay so last cycle was my first cycle on clomid I took it days 5-9 and had sex days 11-21, and got my blood test done on day 23 two days before my period. So I thought was my period. I only bled for three days (that has never happened) and it wasnt as heavy as normal and I didnt bleed for three days straight either. So I take a pregnancy test it was negative, I waited two days took another it was also negative. Now my progesterone levels was 2. So not knowing what's going on with me I called my nurse and asked her if there's a possibility I could be pregnant and she told me there's no way because I didnt ovulate according to the test. So now I'm confused. I looked up some stuff on the internet and read that the test should be taken a week for before your period. So could my test be wrong, could I still be pregnant, is there something wrong? I need help.
