should i get my first period this month?

I spotted only once for the first time on Dec 18, 2013 and again only once on June 16, 2014. My mom got hers when she was 11, I'll be 15 in August. I have recently gotten acne for the first time. I have been craving ice cream for a couple of weeks, and I usually don't eat.ice cream. A lot of quizzes that I took on here said I would get it in a few days and weeks, not a lot of them said months. I have been wearing bras and having pubic hair for 4-5 yrs and have had discharge for 2-3 yrs.
