Over weight and trying!

Hi everyone.

My name is autumn and I have been with my husband for five years and we have been TTC for going on 3 years. I'm very discouraged and I have no clue if its me or my husband or maybe the fact that I'm 300+ pounds and I'm 6'2.I have been trying to lose some tho. I've heard many people say that it will happen but I'm really starting to doubt. Anyways what I'm wondering is there other woman here who are over weight and have had a baby? Or are there anyone out there like me trying and its not happening? Also of anyone has any advice please let me know. Just please don't attack me about my weight. Thanks
