I'm 13 weeks 4 days and literally two days ago I've been having to poop after every thing I eat. At first I thought it was a stomach bug, but now I'm thinking maybe something is wrong. I could eat like 3 chips and it'd make me have to poop. I've been going like 3-4 times a day and I would be having a tummy ache if I have to hold it. Is this normal or should I call my dr?
