Bulging anterior soft spot

Alyssa

My son was born via c section on the 23rd of July he’s a little over two weeks old and today I noticed when rubbing his head that his right side back soft spot it’s kinda bulging and it’s making me super worried the other two are normal and I tried googling and that just worried me more I’m gonna call his pedi in the morning but wondering if anyone else’s baby has this. He doesn’t seem bothered by it at all and he has so much hair I can’t get a picture of it and it’s not noticeable unless you run your hand down his head.
