Missing our Chance

So a quick run down of the dilemma I'm in. I had a HSG done this past week and the doctor said to wait 2 days before we can BD. Then the results came back and showed I had an irregularity in my uterus. My obgyn told me it's a polyp so she scheduled me for a Sonohysterography on Monday. The clinic said protocol is no BD before procedure although my obgyn told me we can keep TTC. Well we decided to wait bc clinic said no BD. It was the same protocol for the HSG as well. I have been so worried that I'm gonna miss my chance this month and I used a digital opk yesterday and today. Well I got my blinking smiley today which means I have high fertility! I didn't get my solid yet. I just know it's gonna come before my procedure!! I wanted to try this month bc I have read how women got pregnant after a HSG bc it flushed out their tubes.  I think we are gonna miss our chance this month.
