Hi! I Have A Loss Of Libido Problem.. Im 27

Hi!
I have a loss of libido problem..
Im 27 years old, have a 5 month old baby, and been married for 3 years now. My husband and I work together well, but sexually I dont have a Desire.
The problem accured maybe by the 2nd year of marriage. I just didnt have the Desire to have sex, not just with my husband but in general. Sometimes sex disgused me! I dont understand whats wrong.. We dont have sexologist in our country and I just dont know how to get my libido going.. Please help!
