Does anyone else experience this?

9 weeks tomorrow.

Constipated-ish with one incomplete bowel per day for maybe an entire week followed by a few days of cramping, a few bowels, pain and what feels like impending diarrhea? I have no idea. I am not taking supplements so it cannot be the iron in the materna. I'm clueless it its normal. I see the doctor tomorrow was just curious if anyone else has this?
