Birth control + stomach aches

Has anyone got frequent stomach aches and diarrhea from the birth control pill?

I was on it for 7 years before I had my daughter and haven’t been on it for 3 years now, started again 3 months ago (just finished my third pill pack) and have been having stomach aches and diarrhea almost daily since I started.

I have an appointment with my doctor and we previously talked about dropping the dosage from dizziness I was having but that went away, this hasn’t.
