May be pregnant?

I've been vacationing like crazy for the past month with and without my husband. And I lost track of my pills. Last week I didn't take any pills because it was my period week so I was just going to start fresh and new after my period was done. Well I still haven't gotten my period I last got it on Aug. 19th and tomorrow will be five weeks of not having one. 
Should I even tell my husband that I'm thinking about taking a test? (We had a miscarriage and don't want to get his hopes up)
Or should I just wait and see if it's from all the traveling and my body is just out of whack?
