CD27, late ovulation 6 DPO

So I’ve been cramping on and off past two days. I ovulated late this month confirming with OPK, of course my annual with the OB is Monday the 17th. Knowing it’s too early to test and it’s possible cramps are pms, do I mention a possibility so they test at the doctors or test prior ? By then I’ll be 10DPO expecting AF the 23rd.
