Really painful sharp pain in uterus..? 5 + 2

This happened last time I was pregnant and I ended up miscarrying so I was wondering if it's normal or not. I know cramping is okay but I'm 5 weeks 2 days today and I just had a sharp pain that was so bad it woke me up out of my sleep. It lasted about a minute. Have any of you ever experienced this? Really freaked me out last time and this time it's freaking me out even more. I'm gonna call my doctor when they open this morning but I was wondering if it's ever happened to anyone and if it meant anything bad for you? Thanks so much
