Hi girls I have questions. I don't have a mom to talk about period stuff with..?

I jut turned 15 and still havnt had my first period. I've had very regular daily discharge for almost a year now and this week I havnt had any at all. Also I'm having random sharp pain in my ovaries. I've only cramped up like 3 times though this week and they were tolerable. So my question is do you think my period is coming soon? If so how far away do you think it is?
