second time having diarrhea 😪

Ahrisa • We are patiently waiting for our son Zyire Ahmin Koiner to arrive on December 31st 2016 💙
I had diarrhea at 28 weeks like four days in a row i told my doctor and she told me to take immodium . Now im 30 weeks and just woke up with a upset stomach and diarrhea again . Is this normal does anybody else go thru this ?
