Breakthrough bleeding on pill getting heavier after 14 days of bleeding & 16 days being on pill for first time. Will this stop on my pill free wk?

Probably not. You are having breaktroughbleeding caused by the external hormones you are taking. Ask your doctor to see if he/she would recommend stopping for 5 days now, then restarting a new pill strip or have you take two pills a day for a few days. This may stop the bleeding you are experiencing. Sometimes a different pill will help also.
