Okay... could this be a sign im close to my period?

Okay, sense last night I have had a lower stomach pain on both the right and left kind of going across... I have discharge (Sometimes a lost, sometimes not at all) I have some under arm hair (some turning black... and some still peach fuzz) and hair down there.. right now I have dizziness headaches... I went to bed late.. BUT when I woke up at nine... sometimes I do that and never get dizzy...! Is it my period coming or something else?
