What side effects did you have with progesterone?

My Dr put me on 100mg of prometrium (progesterone) two times a day for the remainder of my first trimester. I’m also on daily baby aspirin since I have a history of recurrent miscarriage. I’ve been on it for a week and felt relatively fine but now I have diarrhea (last 2 days) and more headaches pretty constantly along with my normal nausea. I think the diarrhea could be caused my diet since it hasn’t been the greatest but I’m just wondering if anyone else has had diarrhea while on progesterone??? Or what other symptoms you’ve had.
