Clomid and ovulation day.

Stephanie
This is my third round of clomid. First round I didn't ovulate. Second I ovulated on CD19 and conceived but ended im a chemical. I'm now on cycle 3 on CD 18 and hoping I ovulate soon. I took it this cycle on days 3-7 instead of 5-9 hoping to ovulate sooner but nothing yet. Getting discouraged. What day do you ladies usually ovulate on clomid and did they end in successful pregnancies? Nervous.
