cramps at 6 weeks pregnant is it normal?

I'm getting cramps and I'm 6.5 weeks pregnant. I haven't had my ultrasound yet I go April 10 so just over a week away but I seem to be having cramps. Not a lot they aren't overly painful just makes me worry. I've never been pregnant and am wondering if this is normal? I am also on progesterone suppositories and have been since March 1 after my egg retrieval. There isn't any bleeding so I'm hoping the cramping is normal. Sometimes I also cramp after I go pee? Is that a bad sign or is everything normal? Help! I feel kinda stressed out 😞
