I had similar symptoms too. I started the pill a month ago, and everything was bouncing off the walls.
My period came a week early, and lasted 14 days!! My doctor said this was normal for the first pack of pills, and not to worry about it. Finally, I stopped bleeding, and I just started my second pack of pills 2 days ago.
The brownish sludge is normal too, it happened to me and it lasted a couple of days. Don't worry about it.
If this continues though after ur 3rd pack of pills, you probably need a new medication. Ortho tricyclen lo might be too strong or not strong enough for ur body.
