Cramping making you nauseous?

Hi ladies, just seeing if anyone else is having similar symptoms. I find I’m feeling a bit crampy, or ‘heavy’ around my uterus most evenings and some mornings. No blood at all (not even spotting). A heat pack seems to help, but I’m trying not to use one much because I’ve read they should be used in moderation. Sometimes I’m actually quite nauseous from this feeling. Is this normal? Or should I chat with my doctor about it? Feeling a bit nervous, I’ve never been pregnant before 😟 I’m 5 weeks 4 days
