Another thing to keep in mind, when in doubt, call your doctor. Don't feel like you are bothering them or like you don't want to be a nucence. They a very well paid, and they are very well paid by you and your insurance company. So if it makes you feel better, call.
In the past when I have gone on the pill, after not having been on them for a long time, I experienced breakthrough bleading ( very light). I was told it was not unusual, and it did not last long. Do what is comfortable for you.
Good luck
