i can't get it up

my husband and i have been trying to concieve for over a year and a half now. I have PCOS and im 33 so its been difficult and so far absolutely nothing. one of my main issues is i dont ever feel like having sex. i used to want to at least 3 or 4 days a week, i even thpught my sex drive was a little too high but now its zero.... we have sex like 3 times a month which is usually just during ovulation week. i love my husband we have a ton of fun together and i enjoy it when we do but getting there seems impossible most days. does anyone have this issue? anyone have any remedies or suggestions? i really want to have a baby and i think he wants it even more than i do if thats possible we just have to figure out what we can do to help me "get in the mood" for lack of better wording
