Where's my rainbow baby?

I just need to type to get off my chest! 
I've had 3 miscarriages, all in a row..  and we are still trying for our rainbow baby.. And seeing a BFN in between sucks! It really sucks! 
I know I'd be a damn good mum, my fiancé would be an amazing dad.. Yet no luck. I don't know how to feel after nearly two years of this!
