Dtap booster making me feel exhausted

So yesterday I received my Dtap booster shot which is now recommended for pregnant women to get before 32 weeks. Well today I’ve been feeling extremely fatigued, like so tired, zero motivation etc. Plus my arm is super sore. Could the fatigue be a side effect of the shot. I know it says you can feel fatigued right after but this is the next day. I got it at about 6:30 pm last night.
