Late?

Hi, I’m currently 8 days late, and have been TTC for 2yrs, so you can imagine my Brian right now with thoughts of been pregnant. I’ve done test and all come out a clear negative, I’ve an app tomorrow. But I wanted to discuss the feeling I have.

I have a constant pain in the lower part of my belly and almost a “sore” feeling in my fufu.

No signs of anything and no other symptoms. Please can someone tell me if these symptoms I have are due to pregnancy or something else?
