I don’t know anymore

Husband and I are both 29.

I’m going on my 6th miscarriage.

I take pregvit prenatals, I walk everyday and lift weights ever other day. Before miscarriages I was 130lbs, depression and bad choice has ballooned me to 180 lbs.

Went to fertility clinic and tested husbands sperm, there fantastic. Clinics closed due to pandemic. So is there anything I can do to get and STAY pregnant. Losing hope and giving up on the idea that It will happen for me.
