I started having light cramps about five hours ago. I know that is normal, however they don’t normally continue..this past hour I’ve been have having pelvic pain. I’ve emptied my bladder, drank more water and I have a pillow between my legs which is helping a little. This never happened with my first two kids even though I had placenta previa early on with both (which corrected itself rather quickly). Should I be worried?

I believe I am 8 weeks today based off of my ovulation date.
