Pregnancy Signs?

Af is not due until the 25th and I ovulated on the 11th so 9dpo and I've been feeling like pressure on my chest kinda like indigestion but different I have to change my body position to sooth it, today I've had minor cramping in my lower abdomin and milky/clear discharge, also been having super bad has pains! And diarrhea all of a sudden! (I have never ever gotten period pains before in my life so I doubt it's a period symptom) also I've been feeling sick after meals lately as well or turned of eating them completey! Any one experience similar or the same at 9dpo? What do you think?
