Hello I'm new to this app

Hello , I'm new to this app . I recently found is in looks of a little help getting pregnant with baby #2 . This is my story , my husband and I have been together since we were 16 years old . We never used any birth control and our daughter was consived 1 year later. Our daughter is now 7 years old and we have be trying to have baby #2 for 6 years now . We never have used any birth control. I also stopped getting my period regular like I use to (every month for 5 days) my last regular period was sept. Of 2010. I've gone to the doctor and all he said to me was that I gain too much weight after having my daughter . I use to weight 140 and I now weight 190 . And he said until I lose the weight I cannot conceive or have a regular period. And that he can't really help me. I got extremely depressed now and am going to talk to someone for it . I'm sorry just had to vent my situation and see if anyone has had the same problem as me or give me any advice on what I could do .... I'm really losing hope here. I also can't take one more person asking me "when are u going to have another one? Your daughter is 7 already" thank you for reminding me as if I didn't know and fyi we don't use birth control so it's not like we are proventing it .
