Anyone with PCOS trying to get pregnant.

Hi, I am 36 years old and I have PCOS. I have been married and trying to get pregnant for almost nine years.
We recently were able to get pregnant for the first time after having both lost 35 lbs each on a special diet. The loss of this pregnancy sent me back to old habits and I have gained 6 lbs back. We have had no luck in the past few months since we were ready to try again. I keep thinking if I could only get it together and diet again that I could have another chance. I am almost 37 and can't help but think I don't have much time left. The only other thing that we did during the time before we got pregnant was try fertility treatments the month before witch did not work. We got pregnant the month after. We have been going through hardships lately and can't afford the treatment again right now. Too much money. I have heard of people doing fundraising to get fertility treatments and even adopt. I was wondering if anyone has done this or known someone who has done this. Me and my husband are parents without a child and it has been hard on us and our family who see that we would be such caring and wonderful parents. Any information that you could share would be wonderful.

Here is the video I took of when we found out we were pregnant before. I miss my angel baby so much. Please help if you have any info.
