Chemical Pregnancy?!

I took three cycles of Clomid. My period never came after the third cycle. I took a test the day of first missed period. I got three positives. Ended up bleeding a few days later which I think was my period, only for a day and a half. Then I went in for a blood test which came back negative for being pregnant. :(

Calling it a chemical pregnancy.

This would be my second miscarriage.

Now the doc wants to prescribe me more Clomid. Anyone else have this happen???
