fertility testing and question

LT
So I had my first round of testing. My LH and FSH looked just fine. They bumped up my thyroid meds a bit, and saw I had some low estrogen. But because my other levels were good, and the fact I was getting positive opk the last two months, she's pretty sure I am ovulating. But, to be on the safe side, she is referring me to an obgyn fertility specialist, scheduled me for an ultra sound, gave me more bloodwork, and my SO is coming for his own testing this weekend. Never did I think that this is the path I would be going down. 
So my question is, anyone else with low estrogen but ok numbers otherwise been successful getting pregnant naturally?
