Ovulation?

I was just wondering if this was ovulation discharge, or what it looked like. I don’t have anymore tests to test but every month I tested it was negative, I don’t know if I’m just not ovulating & still having my period or???? I went to the doctor and had bloodwork done, she said my thyroid is fine and I don’t have PCOS so idk why my husband and I are having such a hard time getting pregnant. He got tested and his sperm count is fine, despite his thyroid issues. My mom has lupus & hashimotos disease. I really don’t know why it’s been a year and a half and I haven’t gotten pregnant. Infertility doesn’t run in either families. Does this look like ovulation? I don’t get it everyyyy month but sometimes. I’m really stressed out. Sorry for the vent.
