Celexa while pregnant

I’m 10+3 and I started celexa last night. I took it around 8pm and then woke up around 1130 with a bad upset stomach. I had to stay in the bathroom for about 45 minutes.

My question is, could this be normal from starting a new medication while pregnant? I took it with food, but maybe I shouldn’t have? Or is it coincidentally from some food I ate yesterday?

It is now almost 1:30 am and I’m feeling a little better after eating a piece of bread and drinking ginger ale.
