cramping 7dpo

Ke

My cycle is very regular. I know first thing in the morning if my period is coming or not. I have constant pms symptoms at the same time every cycle. ovulation day was the 6th, I've been feeling period like cramps lightly for the past 4 or 5 days. I don't get period cramps until the day my period starts. I know it's too early for real pregnancy symptoms but I'm not sure what it could be. Any advice? af due the 19th, trying to wait and test then.
