Suggest Remedy For Painful Irregular Periods

Hii...soo Im an 18 year old woman and my problem is that I have irregular periodss, or not exactly irregulars but very early...they last 24 days almost always, last time lasted like 22 days. I wanna know if, first of all is it normal they last 24 days? or 25? And well, I have gone to my gin before about thiss, and she gave mee hormones last year to regularize it, and becausee I had a lot of pain in one of thosee, which is not normal on mee, but I dont have that problem no more, just the normal disconforts the first two days.
