Successful Stories of Clomid user?

I have a long history with clomid that goes back to 05. In August of 05 did 2 rounds of clomid(50mg) and got pregnant, but miscarried. Then in December of 05 did another 2 rounds of clomid(50mg) with 500mg of metformin a day and got pregnant on my second try. And had a healthy 9lbs 1 oz little boy who is now 3 years old. Then at the end of October of 08 started my first round of clomid(50mg). Didn't ovulated, so doctor had to up my dose in December to 100mg and I ovulated, but didn't get pregnant. So in January of 09 I did another round of 100mg and didn't ovulate, don't know why. So at the end of February(09) I did one more round of 100mg and ovulated and got pregnant, but at my first ultrasound at 7 weeks the baby was not there. Went 3 and a half weeks of ultrasound after ultrasound of thing and ended up miscarrying at 10 and a half weeks. So we waited 4 months and at the end of September 09 we started another round of clomid(50mg) along with 500mg of metformin day and I had to take it everyday til I was 9 weeks pregnant. I ovulated, but didn't get pregnant, so the doctor up my dose to 100mg and for some odd reason I didn't ovulated. So in December I did another round of clomid(100mg), don't know what happen, but I didn't get pregnant. So in January I did my last round at 150mg and the day my period was due I took my hpt and got my BFP. Went in for my first doctor appt at 7weeks and at first didn't see anything, so went some where else and they found my little bean, now I'm 10 weeks pregnant.
