My cycle is late after 2 rounds of clomid. My 1st round was 100mgs for 5days and 1 Metformin 850mgs (which I've been taking for 3yrs). The 2nd round was 150mgs for 5days, an HSG test (opening my tube, the only that I have) and this website that calculated my ovulation that told me to have sex and I did and I'm 2days late. . . We're excited!!!!
