First time trying. Weird symptoms

My husband and I sponatiously decided to try to conceive this passed ovulation (8 days ago). We had unprotected sex on the 29th. I took an ovulation test the next morning and the lines were strong and positive. Since 3 days passed ovulation my breasts have been sore. I've randomly been getting super exhausted. And I think I'm eating more. I've noticed some nausea but I think my brain is making it up. Do yall think I'm pregnant? I have 5 more days until I test and the wait is killing me. I don't usually get sore boobs
