Trying to conceive

So I've been trying to have a baby for about four years now it's extremely hard I track everything so last year I start going too and ob just for it she did blood work and ultrasounds my blood work showed my progesterone level is low and the ultrasound showed I have pelvic congestion syndrome all she did was tell me I need to loose weight and put me on metformin I'm not having no luck I'm getting so frustrated I already a nine year old I don't know why it's hard
