Post-ovulation mini-cramps

We have been TTC for about 5 months, but this is the first cycle I have been tracking bbt & paying attention to CM.

I’m DPO 6, & ever since predicted ovulation this cycle (no opk), I have been getting these quick cramp-like twinges in my ovary areas. They are two or three second mini-cramps that come & go a couple of times each day.

I understand that it’s too soon for any pregnancy signs to show, but I’m interested to find out if anyone else has these? I don’t think I’ve had them before, but that just may have been me not noticing them.

Posting a picture of my chart for good measure (missed yesterday’s temperature on accident, oops!)
