Pill trouble

I got put on the pill back in August. September I went in and they told me to just take the first three weeks of pills and not the white ones and I wouldn’t have a period. Said it was perfectly healthy and I would be fine. So I went on and didn’t take the white ones. I’ve now been bleeding for over a week and it was only a little at first and now it’s getting heavy. Anyone have anything like this happen? I’m not skipping over the white pills anymore.
