I had somewhat similar situation.
DD1 was born when I was 36 after 2yrs of trying/diagnosing. I have low progesterone, so the fix for me was a few rounds of clomid-I was very lucky.
I was ready right away after her to start trying again (after the raging birth hormones resolved a bit and I got a little sleep that is!). We just didn't TTP for the first year, and that was fine, but at about 14months I went back to get Clomid again. My Dr. wouldn't give me it until...
