Period cycle

Madison

Ok, I need some help y’all😂 so I haven’t gotten my period yet and it’s cycle day 33. I don’t know if this is normal. My period instead of the starting date being before (one period starts on the 10th but my next starts on the 8th) my period date is always later than the previous, (one period starts on the 10th but my next starts on the 13th) is this normal? Because I am sexually active and all this tracking is getting a lil worrying to me. Can someone please help me ease my mind a bit here?
