Tests tests and more tests

Heather
My husband and I have been ttc for 1.5 years. I'm 23 he's 24 we've been married for 3 years. We're both very healthy and have no reason to believe that we can't have children. We recently went to a fertility specialist and after several blood tests and ultrasounds she wants to go bigger. Next on the list is a tubal x-Ray. 1 of all has anyone ever done this?! Any insight on this? I'm nervous about it. After we do that she's debating putting me on hormones. 2nd does anyone have any recommendations? I just feel so dumb... Idk what's wrong and I feel like this is all my fault... I'm starting to get quite discouraged.
