Weird rib cage pain after baby dropped

It feels like someone is squeezing my rib cage, it's so sore. I can still breathe, but sneezing, laughing, and coughing make my ribs ache. Baby dropped a few days ago, I doubt the two things are related but it's the only thing I can think of. It's not 'go to the ER' painful, but it does hurt. I'm 35 weeks currently and I'm a first time mom so I'm not sure if this is normal.
