Bleeding, pill

Hey everyone! I just started taking the pill (lo loestrin fe) a week ago, and everything was going fine until I got super sick (a stomach virus I think) on Saturday and didn't take the pill. I then started bleeding (like I have my period, not just spotting), on Sunday morning and am still bleeding as of now. I took two pills last night to compensate, but I'm not sure if I should be worried. Any advice would be appreciated!
