My husband has crazy high sperm count, so far no issues on my end but we are 17 months TTC

I am feeling hopeful after some positive news, but my husband had his semen analysis and it came back with a count of 832million and 539million with good motility. Is he a freak or what?! How am I not pregnant? I ovulate every month. No PCOS. Hormones completely normal. I am getting an HSG in a couple weeks and a SIS to see if I have any blockages. I’m at a loss. It has been 17 months. Is there such thing as too high of a sperm count????!!!
