I don't think talking to a professor can ever really hurt you, but I don't think it will necessarily help, either. I got rejected from places where I had reached out to professors and offers from places where I hadn't. I honestly wouldn't worry about it this late in the game. I think it's mostly helpful when you've not only contacted professors, but also have some sort of connection to them through a professor at your own institute. If there's anything I've learned, it's that this whole process is a gamble. It's nearly impossible to say what will/will not get you in. That being said, good luck Explorer33!
