Keep taking it as usual. Breakthrough bleeding and/or spotting is a common side effect of being on the pill and definitely not a reason to stop taking it. In fact if you stop taking it you'll mess up your cycle schedule so I would not stop taking them.
Thank you for the response. This is the first time that this has happened in the three years that I've been on it so I wasn't sure.
It can happen anytime regardless of how long you've been on the pill. The longer you stay on it sooner or later it would happen at some point. It's the #1 most common side effect of being on the pill.
