Seriously Overweight TTC #3

My husband (of 1 year) and I have been TTC for over a year now. I'm 34, mother of 2 (with late husband), and 350 lbs. I've dropped 50 lbs in the last 5 months and I'm continuing to lose weight. I was just wondering if anyone else was in my situation and what did you do to get your BFP?
