My Sex drive is ZERO

I have been trying to boost my sex drive, but no luck. Currently I don't have any desire to have sex with my husband. He doesn't know my situation, but I always use my baby as reason of not being able to have sex with him. My LO is 7 months and I get so busy some days . Anyway, We were doing it 4 times a week, but now It is only once a week or once every ten days . I'm worried about losing our relationship. This is really out of my control and this makes me hate myself. I feel like sex is boring and I do it just to satisfy my husband needs. I'm 24 years and I had my baby after 4.5 years of trying. I was really worried about miscarriage, so we decided to minimize the sex into twice a month when I was pregnant. My thyroid is under active and I stopped taking the drug 3 months ago.
