Weird cold tingly cramps??? Help

Miranda

Last night as I was falling asleep I was laying on my back and I started to feel these sharp tingly and kinda coldish feeling cramps in random places around my uterus. I’m sorry if this explanations is hard to understand but I started birth control 2 months ago and I want to know if these little tingly cramps are just a normal side affect or should I watch out for them.
