Negative at home sperm test

So my husband and I have been ttc for 4 years. Im 23 and he's 25. We are in our prime years.. male infertility runs in his family so I finally got an at home sperm test a few months ago and it came back negative, meaning low sperm count. Has anyone else still gotten pregnant after a negative sperm test?

I'm currently 33 days late on my period, but I've had an incredibly rough past month due to my house burning down and currently being 'homeless' and jobless. I said homeless because since the house I've had to move on my husband's 18 wheeler and live on the truck with him (he's a truck driver). So I've gotten depressed. Im sure my missed period is from my depression I just really want a baby and don't want to get my hopes up. I had strong cravings a few weeks ago.... I'm not much of a meat eater but for 2 weeks straight I ate steak basically every other day.
