having contraction like pain

Isabel • Anything can happen

I'm 10weeks 5 days and I'm having these contraction like pains that come and go across my stomach going horizontal...should I be worried. I haven't been eating very well do to nausea and also haven't been takin my prenatal vit either cause I feel sick ALLLLL THE TIME. this is my 3rd pregnancy and it's completely different. but right now my main concern is this pain...any help or advice is greatly appreciated thanx
