I get that sometimes, like these jolts of pain? Its most likely round ligament pain.
BUT!
I went to the ER for that similar pain and left with the diagnosis of a UTI. I would have never known it was a UTI cause I had no urinary pain or symptoms besides those jolts of pain. I would say you're in the clear but always monitor yourself and be extra cautious of anything out of the ordinary
