Changes in menstrual..

Usually I start every Wednesday/ Thursday and this week I started Thursday. I don’t remember my periods ever being this light and I only have them for like 4/5days because I’m on the BC patch and I put it back on on Sunday.

Yesterday I started and my period was heavy but light. Enough to fill up a “be radiant” pad. I’ve had the same pad on for like 6 hrs and I’ve bled maybe a tablespoon of blood and it’s not even red.. the blood is dark red/ brown like it’s old blood.

Is this even my period?
