Pregnancy symptoms

Hey ladies. Just want some input. My husband and I had sex on August 2nd, according to the app this is my ovulation day. On August 7th & 8th had cramps. On August 9th my boobs started hurting really bad, the pain has stayed but isn't as bad. I'm trying not to get my hopes up but I never have boob pain. Any stories to help me not feel like I'm going crazy?!
