Fell down the stairs at 34 weeks...

So this morning around 10am I fell down my stairs I mostly hit my back, but at the bottom of my stairs we have a wine cabinet and my stomach and front end went straight into it. I felt the jab to my stomach and called my OB I’m going to see them in 13 minuets. Am I overreacting by calling them? Baby hasn’t been kicking much at all, and I’ve had horrible pains from my back that radiate to the front and then I cramp. I’m just worried, but I don’t want my doctor to be upset that I called and came in (he’s not mean I just get anxious).

Update*** I just got done at the doctors and baby girl is okay, I only have a bruised back so I’ll have to ice it. Thank you so much to everyone who responded it means a lot to have support at a time where I’m petrified of something bad happening.
