provera and no period??

I have been taking provera to induce my period for 5 months and i just stopped my last pill ( taking them 7 days if period hasnt came) like 2 days ago and still nothing, i always get it the next day after taking my pills or even if i forget them and only took two pills i still get my period but nothing... i usually have symptoms of a period but nada. I am emotional these past days so could i be pregnant??
