Wedding Stresses!

So the countdown is on until I get married, even after my venue screwed me over 2 months before the big day, leaving me to start over and plan everything like a new venue, caterer, reception site and everything, but on the bright side we're already married but we didn't tell anybody. He's in the Army and was going overseas so he asked if I would marry him earlier and of course I said yes! The dilemma is his mom is kind of crazy, like she gets mad every year he spends Valentine's Day with me and not with her even though she's 8+ hours away and I'm never more than 2.. I'm getting nervous she'll find out sometime during the wedding weekend and ruin everything. Should I just ignore this feeling, forget about her, and focus on the final planning or should I be concerned?
