Diarrhea, pregnant???

I’ve had diarrhea for the past 4 days, not all day just a few times a day, especially in the mornings. I’ve been coughing and sneezing and having a runny nose and I just ruled it as a symptom of my cough. I looked on here and a lot of people said they had diarrhea early in their pregnancy. Did you have diarrhea in your early pregnancy? As far as I know I’m not pregnant.
