Periods!

So like bleeding isn't enough. Lol. Anyways I've had light periods for a couple years now, and my cycle lasted 36 days before getting my period when it's usually 27- 32 days and it's rare for it to go longer than that. But I noticed yesterday I stared to cramp and saw blood, but then cramps went away and I bleed the lightest amount and I didn't bleed until this morning and it's just weird.
