Not sure what's going on

I had found out May 1st that my babies heart stopped beating, then the miscarriage started on Mother's Day. My SO and I have tried again a few times since then. Now I'm experiencing everything I want when I got pregnant last time except the tender breasts. It's also slightly painful after intercourse. I took a test about a week ago and negative. My next dr apt is not till the 17th. Could this just be my hormones going back to normal?
