I'm too afraid to test

I had an HSG done on CD 10. Everything went well and all was clear. I have a regular 28 day cycle, but this time it never really came. I started spotting on CD 33 and have been for 4 days now. I called my doc and haven't heard back yet. I've been cramping, had a back ache, I'm exhausted, and I haven't had a solid bm in weeks.

I'm just too afraid to test because my husband and I have been trying for a baby for nearly 2 years and I don't want to see another negative test. I don't want to get my hopes up, but this has been the closest to having pregnancy attempting I've ever had. My fear is the HSG messed everything up.
