Miscarriage

I am supposed to be 8 weeks and 5 days pregnant however, ultrasounds have determined I'm having a missed miscarriage.

I see a Dr next week to discuss options to pass the tissue.

My question is my husband is a heavy drinker and a month before we got pregnant he did a sperm analysis and his morphology came back at 1. Could this be a cause for the miscarriage?

Thank you 😞
