... started spotting (brown discharge) and now I have a light flow. I still have a week and half left in my packet. I haven't missed any pills and take them on time. I've never had this happen to me before.

I leave on a vacation next month and I do NOT want this to happen while I'm there. Will this mess up my cycle? Should I still take my pills regularly... or should I stop. (I don't take any pills on my 7 day break). Or should I go to a doctor?
