We've been trying for our third for 16 months. I've already tried clomid 50 mg and 100 mg prescribed by my regular ob/gyn. It didn't work. She recommends we see an RE. I'm only 29, and my husband is 30. We have two children together, ages 6 and 8. I've been tracking my cycles for 6 months, and the non-clomid cycles have all been annovulatory. The clomid cycles looked ovulatory, but my progesterone was low, so apparently I didn't actually ovulate. Should we keep trying on our own for another 6 months, or just go ahead and see the RE? What would you do?
