Quick question!

AF is due to begin this weekend! (Hopefully she doesn't show) however today I've noticed that I feel a lot of tightness in my lower abdomen, when I breathe in, cough or sneeze I feel a lot of pulling/ tightness. Breasts are sore and I'm very bloated. I feel like I'm mentally convincing myself it could be pregnancy symptoms even though AF is right around the corner! Any thoughts? Or same experiences?
