ttc advice?

My husband and I have been trying to conceive for over a year now. But no luck. So I went to the obgyn and started infertility and they tested my hubbys sperm and said it was good not great but good and that I was perfectly normal. (I thought I was the problem😫) then after all of the testing and what not a few months ago the male doctor who told me the results of our tests told me I had to lose 30 lbs in order to continue any treatment and keep the weight off  while ttc for a year before we could do anymore treatments. (As it is I'm already really insecure about my weight..) is there any advice that would help us get our miracle? Any advice is welcomed. I would try the preseed but we don't have the money for that kind of thing at the moment..
