cramps at 5 weeks..

Have any of you ladies have or had cramps at this stage??? I've been experiencing it. Yesterday was worse and I went to the clinic and the doctor  didn't want  to make an ultrasound 🙄 just a vaginal exploration and she said it's a good sign that I have no bleeding or weird discharge or symptoms of UTI. she said it CAN be normal but we have to wait. I'm worried. 
Have you ever experienced this??? I need to calm down ahah
