New pill, no period!?

So I start mirvala two months ago after some major troubles and problems with a previous kind. I hadn't had my period for two months because of the last one (not pregnant went to the doctor) now I took the first month got my period right on time, stopped pills Monday period came Thursday, it's always Thursday. Now the second month is over and now I'm late. It should've been today but not even some cramping or anything... :/ should I be concerned or wait it out? I'm an hour from doctors or a store to buy a test! Thanks in advance
