Looking for hope

I had a meeting with a fertility doctor today that I've been seeing off & on since May of last year. We were scheduled to speak to someone about treatment options in late July & found out we were pregnant same day. I ended up miscarrying twins in September. The miscarriage was brutal. We had tried for years & were blessed with 2 & then both just gone for no real reason that could be determined. We waited a bit before trying again because I was so afraid of repeating the last results. We finally started again December/January & are now 9 DPO waiting again. I met with the doctor today & she has concerns & ordered a bunch of tests & then we're going to explore all of our options assuming my period comes this month. I've had a lot of symptoms but it may all be in my head as I haven't even had a faint line. I guess I'm just looking for some words of encouragement. I am 34, 35 in October. I am overweight but i have totally changed my diet & can not seem to lose any weight, thanks PCOS. I'm also a type 2 diabetic but well managed without insulin. I'm just starting to feel like it's never going to happen for me. I literally have HUNDREDS of tests in my house & test like a crazy person every day. It's quite sad really. I just so badly want my own baby.
