trouble getting pregnant

Me and my husband have been together for 6 years and never used a condom once,  we've been married a little over a year now, and wanting to have babies. My periods have never been regular and it got to the Point where  I didn't have one at all for over a year, so I finally went to the vagina doctor and she told me I didn't have a period bc I had gained so much weight, so I've been tying to loose weight. She also ran blood work and told me my testosterone was high and I can't figure out how to lower it. Anyone have any tips? It's really starting to get me about not being able to get pregnant..
