My sex drive is gone

Borgs • TTC for 3 years with hubby .Diagnosed with PCOS at 16, Hoping for rainbow baby after my miscarriage at 11 weeks with twins in Jan 2016 ❤️💛💚💙💜

I feel so bad for my husband as all he wants is to have sex but my sex drive is just gone. We will go through spurts where all I want to do is have sex and next I don’t want it for month and we could go months and months if I didn’t feel so guilty. I want a baby and I want to TTC but my sex drive is such a bummer and I don’t know why. Any advice or encouragement would be great! I feel like such a shit wife
