Baby Roland through IVF

Hi my name is Abigail, I have pcos and suffer from infertility really bad. I have been trying to get pregnant for 6 years with clomid, letrozole and they're just not working on their own. My Dr told me next step is IVF and Im struggling financially to come up with the costs for it. I want to be a mom so bad others think it's just a joke but to me it's a dream to hold my little one some day. I cry behind closed doors and put happy on for others but it's really killing me. Please help ?
