Vaginal cramps?

Katie
I'm 5 weeks today and I've had dull cramps the last two weeks but I know those are due to the uterus expanding for the baby. But this morning I had a sharp vaginal pain/cramp for about 5 minutes and another sharp pain/cramp just above my vulva on the right side for a few minutes. Should I be concerned? I usually only get those when I'm menstrating. Thanks!!
