Period twice maybe??? Help?

Okay so maybe like a week ago I started to bleed but it was only like a watery pink to slight red and a tacky brown with some brown uterine lining and it lasted about a week and a half . Then I’m good for a bit with every once in a while having brown spotting again. Now today it’s dark red but still watery , not like my usual periods (no clumping or anything yet). I’ve never had a period like this before? I am taking Audra birth control. Does anyone have any answers? Is this a period or is this something else? I’m literally 21 and I have been having periods since I was 9 and I’ve never had a period like this?
