Stomach discomfort

Sarah

I’m 4 months postpartum and I’m having discomfort in my stomach. I haven’t had a period yet and I’m breastfeeding and supplementing with formula. Since Friday I’ve been having discomfort in my stomach and lower stomach and I can’t tell if it’s cramps, maybe my period gearing up or something else. I have an appointment with my doctor but wanted to see if anyone else had similar symptoms.
