anyone?? 😊

So I usually have period cramps when I do cramp, af not due till a few days after Christmas, this whole week I've had on and off pinching just on one side last night it felt like it was right in the middle and a little stronger, does ovulation do that all week?? what is the difference between the two feelings? I bd'd a week ago tomorrow so I feel like and "implantation" would be way to soon??
