Pepto-bismol has aspirin in it you should not take it!! Just asked this question at my last appointment!
Diarrhea usually clears itself up, I had it bad in early pregnancy and it stopped on it's own, drink LOTS of water, and drinks with electrolytes, like gatorade, etc. Ask your doctor about any medication you're unsure of, especially if you're high risk!
They are little green tablets. I'm not sure abt the pepto though
My dr says its okay to take the over the counter anti diarrhea meds. I've had to take them myself.
