Cramping at 12 weeks

Lisa
So today I was woken from sleep at 3am with sharp cramps to my lower abdomen. No matter what I did I couldn't make it go away. I was already scheduled for my prenatal, so I waited and my GP got me an ultrasound. 
My peanut was moving like crazy, heart rate 152.
☺️ I'm feeling so relieved, but the cramps still aren't going away.
