Ear ache a pregnancy symptoms?

Am
I am 5 weeks 4 days and my ears started hurting a couple of days ago. Sometimes I get blackheads in my ears that hurt, but I don't know if that is what it is this time. My husband says he can't see anything, so I was wondering if it is something to do with being pregnant? And if so what can I do about it? It is starting to hurt so bad it is running into my jaw and is making it hard to eat and sleep. Help is greatly appreciated:)
