6 weeks 4 days cramping

Is it normal to have sharp consistent cramps in my lower left pelvis area? It just started a couple hours ago but doesn't let up for more than 10 minutes or so. This is the first time I've cramped this pregnancy and I know it isn't ectopic because baby is in the right spot on an ultrasound a week ago. I'm a FTM and this is my first pregnancy so I'm a little scared 😯
