Red nodule

Does anyone know what this is? I’ve had a couple family members and friends tell me it’s hormonal changes (27 weeks pregnant currently) my SO & I went to the immediate care & the nurses didn’t seem too worried. It has been giving me a numbing/weirdest feeling on the right side of my head (where the bump is) I’m just worrying if anyone experienced this before or know what it might possibly be?? (It’s hard and can’t be popped)
