cramping toward one side, medicated FET

[Anonymous]

In the past when I've had cramping that is skewed to the side during the 2ww, it was a twinge-like pain in my ovary, probably from a corpus luteum generating progesterone. This time it was a medicated FET, so there shouldn't be any of that from the ovary, right?

I've had a lot of constant cramping (I'm 4dp5dt), but it seems not centered with my belly button and skewed a bit to the left. I'm terrified it's a sign of an ectopic trying to implant. It doesn't seem like cramping from progesterone would be skewed in location.

Has anybody had a successful pregnancy that started out with cramping that seemed slightly off-center in a medicated FET (no corpus luteum, so not ovary pain)?
