i started taking my birth control daily as directed about a month ago after being inconstant with taking it for like 3 months & the first period i got after starting it again was normal. and on monday i got my period again ( i wasn’t suppose to get it for 2 more weeks) but it was DARK brown at first and was kinda heavy but the second day it was lighter and was like bright red for a little bit but then it got super light later on the 2nd day and was light pink/brown when i wiped.on the 3rd day it was completely gone and i still haven’t bled since. has this happened to anyone else ? i am sexually active! should i be worried that i’m pregnant?

thank you! 💗✨
