36 weeks and dilated to a 3!

Logan
So I'm 36 weeks and already dilated to a 3! I know it doesn't really mean much since I could stay this way until my due date but it still blows my mind! A week ago I went to L&D for a freak out moment and I wasn't dilated AT ALL! So in a week I got to a 3! She's head down but not engaged and my cervix is still kind of thick but I just can't believe I'm at a 3! 
This is my 2nd so maybe that has something to do with it...any other Mommas have this happen?
