I've been on the birthcontrol pill for 6 months and just recently I've started to take them at odd times. Then I forgot to take them for 4 days completely. I started bleeding before my sugar pills but only for 4 days I took pregnancy test that came out negative all the time. 2-3 days after it came again and but brown. And its getting heavier by the day, what does this mean? Should I start my new pack since I'm 3 days late?

What's happening is that you are not taking your pills as directed.

They are supposed to be taken every day at approximately the same time for maximum effectiveness.

You should start taking them again when you are scheduled to do so.
