pregnancy symptoms?

So AF is due on sundat, but my boobs have been EXTREMELY sore and tender the past week. they usually get sore before AF but nothing This bad. and I woke up today due to really bad back pain and I had to pee, I never wake up in the middle of the night to pee. and I have been soooo tired, I slept altogether 12 hours last vs my usually 5-6. I took a few tests last week but they were all negative but I thought it might be too early. my fertile window was 8-13 and I ovulated the 10th. Do you think it's AF symptoms or pregnancy symptoms?
