Cramping without bleeding

Candace
Yesterday I woke up with severe cramping that rolled in to nausea, cold sweats and vomiting. The cramping was bad enough that my husband had to call off of work to stay home with our daughter while I laid in bed with a heating pad. Within 3 hours I felt pretty normal, no more cramping, maybe a little tired. I am 4w5d and of course concerned about MC. Anyone have a MC that started with a short period of cramping, or have intense cramping with a healthy pregnancy?  Thanks from this worried momma.
