Early pregnancy symptoms or AF?!

Kimberly
I ovulated on 5/26, which was CD 20, and I'm due for AF on 6/5. Today I'm 7 DPO, so I know it's way too early to test or probably to even have symptoms, but it's just a lot all at once. My boobs are extremely swollen, heavy feeling and sore!! I'm also bloated and always feeling really uncomfortable, not to mention really gassy for the past 2 days, and I'm never gassy. Anyone experience these symptoms when they were pregnant or could it just be pms?
