EllaOne pill?

sophie • First time Momma❤️
So about 2 weeks ago i took the EllaOne pill and i got my period Sunday... However, i'm concerned i didnt have any symptoms of my period.. No pains or sore boobs. This is really surprising since i suffer a lot with my periods. I'm on now... It's like i'm hemorrhaging i'm literally bleeding heavily & it normally calms down around the 3rd day but it's still really bad? Just wonderin if anyone had been through the same?? 
Thank you!
