Diarrhea at 39 weeks

Danielle

I had my 39 week obgyn appointment today and I told my doctor that I’ve been having on/off diarrhea for the past few weeks. I also suffer from SIBO. The doctor told me that diarrhea is not a symptom of pregnancy and is making me get tested for COVID. I have no other symptoms of COVID. I’m freaking out and am super confused. Am I wrong that diarrhea can happen during pregnancy and be completely normal symptom?
