Most likely you are not pregnant. If you did get pregnant you would not know that fast. Once you stop taking your pill it usually throws off your cycle. Good luck TTC!!!
I highly doubt pregnancy if you are bleeding heavily. Like mommyagain said, when you stop midcycle with BC it can really, REALLY mess up your cycle. Usually it takes people a couple of months to get the pill completely out of their system so that they are able to concieve.
you threw off your cycle because you stopped taking BC. IT may take a few months for your body to regulate itself. You basically forced a period when you stopped taking the pill and that is why you had bleeding after 5 days. This does not mean that you are pregnant.
