advice needed! should i lose weight before i get pregnant?

Summer

Hey guys! a few years ago I was diagnosed with chronic mono and I was sick ALL the time. I gained about 50 pounds the past 3 years. I wanted to focus on getting healthier and getting rid of mono before I had a baby. I have been eating a lot healthier and feeling a lot better. I lost about 12 pounds but that is it. My husband is finally ready to have a baby and I want to have a baby so bad. I'm 190 pounds and I'm 5'10 My question is, should I try to loose all the weight before i get pregnant or should I be happy where I am at?
