bfn today at 12dpo

18 months ttc. Failed Femara(3months of it) HSG test done everything looks good. Hubby is border line good, also used pre-seed several times. Ugh! I have pcos but mild and I do ovulate on my own. What the heck! 💔😫Any advice is more than welcomed. Nothing seems to make it work for us. We also took a break for the winter to relax which didn't work obviously 🙄. Hubby has tried fertility vitamins from our fertility doctor and seems to have made no difference. We are waiting for our referral to start IUI.
