Help? No period.?

I go my first period on December 6th and I haven't gotten one since. It's been almost two months. I think ove already ovulated because of the discharge I had about two weeks ago. Here lately ly back has been really greasy and I've benn getting a few red spots. I have 2 huge painful zits on my Chin that won't pop and a couple on my forehead and j never have zits. Yesterday I cried because my mom didn't buy bananas and I get really tired. Like almost fatigued at the beginning of basketball practice. Are these pms signs? When does it sound like my period will come again?

Don't panic! Your periods will be really irregular for about a year after you have just started. I remember when I got my first period and didnt have my next until 4 months later!
Also that does sound like PMS which could mean your next period is on its way but not necessarily.
