Ovulation med help

J
How do I get to be put on clomid or any ovulation medicine? Does my husband have to have his Sperm tested first? I had an almost positive OPK and then the next four tests came out super negative... Almost no second line. I'm super discouraged. We've been trying for over a year and a half. I don't have pcos and I got an hsg and everything looked perfect. Idk why I'm not getting a positive OPK but I'm tired of ttc and getting negatives on everything. Please help, thank you.
