Pregnant?!?

CC

I’m not sure when I ovulated as I have irregular periods (previously diagnosed with PCOS) but I have had the worst boob and nipple pain the last two days where it’s so uncomfortable that I feel nauseated from it. I’ve also been so exhausted (still have the same sleeping schedule), weird dreams every night and an increase of discharge. Has anyone experienced this and was it before a BFP? Could this be ovulation?
