Couple of questions! Has anyone had clomid work only one time in the middle? I took 100mg in June and got pregnant but ended in a miscarriage. Just took it again in September but I’m now 17DPO (I think) and still all negative tests and no period. Which brings me to the second question, how far past ovulation has it been when tests finally turned positive? Last time I checked on 15DPO and it was negative but then positive on 16DPO. is there still hope for this round??
