Stomach cramps

I'm just over 5 weeks pregnant and for the past week, I've been suffering from stomach cramps in the morning and late at night. It feels like PMS and constipation.  Did anyone else feel this? If so, when did it stop? My Dr said cramping is neither here nor there, provided there is no bleeding - which there isn't. Interested to read your experience. It's not unbearable, just uncomfortable
