possible blocked tubes - need advice <3

So my husband and I have been ttc for over a year now with two miscarriages both being around 5 weeks. We went to the doctor last month and she wants to check my tubes this month to see if there may be blockage from colon surgery I had back in 2004. AF was suppose to arrive yesterday and I'm absolutely terrified to take a test. I just don't want the disappointment at 5 weeks again...which will be this coming Monday. Looking for some support/advice. Thanks ladies ❤️❤️❤️
