Porn. Help ladies..

Hey ladies, so I've been with my man for 3 years. Him & I have agreed to not watch porn for that's why we have each other for our sexual desires & needs. So the whole time we've been together I have not went on any porn.. Just because I'm 6 days late on AF , I'm stressing if I'm pregnant & we hadn't had sex in a week, I don't think that's any reason to have to behind my back while he's in the shower to go on porn .. Am I being crazy? We both agreed to let go of porn so I expect it to be mutual. I have not yet to confront him about it yet because I don't feel like talking about it.
