7dpo symptoms - nauseous, hot flashes, cramps

Bryony

I think I'm 7dpo today. I've had mild cramps/pain today on the side that I felt ovulation pain a week ago (confirmed with OPK). I've been feeling slightly nauseous, hungry, and I've had hot flashes (I'm 28 so it's no menopause).

Negative pregnancy test but that's to be expected. Has anyone had a bfp after symptoms like this?

I have PCOS so I don't know when AF is due as I've not had a period since May.
