PCOS & Clomid

Mona

So I'm 35 and have been trying for our second child for a year. I've only had 3 periods in that time (one of which was a miscarriage), so I need help to ovulate. I finally got in with an OB and I'm starting Clomid today for the first time! I'm very excited, but am trying to temper my expectations. How many cycles of Clomid did it take for you ladies to conceive?
