Can't take much more.

I'm 36 and my DH and I became pregnant in Feb 2014. I lost that baby in April. After the advised waiting period, we have been trying to get pregnant again with no luck. I am seeing a new doctor and have been on a mountain of prescribed supplements, still no luck. I am about 11 dpo and tested negative again. I have also started to cramp here and there which is usually a sign af is on her way. When will I finally get to see those two beautiful lines? I foolishly let myself get very hopeful this cycle because of the new therapies, but now I am almost positive I'm out. I am truly sick of the disappointment, and I just want my rainbow baby already.
