AF showed today and I'm feeling rather down :(

Really wanted my BFP for Christmas. I swear every month I'm like "this is my month!" And it never is. Really worrying about what could be wrong. Of course I'm thinking all the bad things that could possibly be wrong. Have an ultrasound this week, does anyone know if that could pick up on blocked tubes? Going to see about a hsg procedure if need be as well. Never thought I'd have to worry about any of this. Boy, is it depressing. :(
