BIRTH CONTROL IS MAKING MY PERIOD SUPER HEAVY?!

Kandice
I just started birth control, and my period is super heavy?
I started birth control to help with cramps and help my acne, and my periods are usually light-medium and I usually use lite tampons and have to change after 4 hours, but it was in for 30 MINUTES and I felt something weighing down, so I figured it wasn't in enough and took it out, IT WAS SOAKED! Then I tried regulars and it was soaked within a hour and a half! 
It just worries me because other people have there period lighter on birth control (It's my first period on the pill)
