Normal? Palpitations with coffee

Everytime i drink coffee i make it at home and I always overuse the creamer so you can barley even taste the coffee itself. I only add coffee to give it that faint hint of coffee..

Now that I’m preggo whenever I drink it (I rarely do) I get palpitations for a whole 5 minuets... is this normal? Should I just not drink it at all? I’m 4 months and have only had about 4 cups my whole pregnancy.
