Question about early ovulation

[babydoodle]

Does anyone know how possible early ovulation is during a very normal 28 day cycle? Feeling possible pregnancy symptoms my breasts are so tender they are never tender before AF arrives. But I remember this feeling from my previous pregnancies. I also had some brownish heavy discharge this past Saturday. Due for AF to arrive on Sunday January 22nd. I know we didn't BD mid month so I would have had to ovulate early?

You could have ovulated as early as cd 10 or 11. Very unlikely before that.
