How should I tackle this problem

I'm pregnant and have a young daughter. I've had a body oder problem most of my life but it has been at its worst the last 7 years. People comment on it every where I go and I don't even smell it. Some people I hear say it smells like feet, poop/bathroom or just plain bad. Hearing comments and knowing people are talking behind my back is killing my self esteem and making me a hermit. I want to find a cure for this so I can help my babies if god forbid they start to have the same problems. Doctors act like I'm nuts. Is there some way I can find a cure without effecting the health and growth of the baby I am carrying? What kind of doctor or specialist can help me find a cure? I need this curse out of my life.
