2 years TTC HSG

Feeling pretty defeated right now. 10 dpo and tested with a BFN. I know, I know, it could still be too early. But I know my body and totally know I'm out. I'm on progesterone suppositories so I'll stop taking them in a couple days and wait for the dreaded AF. Now that my husband and I are going on two years TTC we are finally doing the HSG test once I get on day 10 of my new cycle next month. After two years and 1 chemical pregnancy in December I'm feeling pretty done and hoping the HSG test shows something so we can get some answers. Anyone have experience with the HSG and can give me some advice? Thank you!
