Took bc pills late 2d in a row and a day later, i have period-like bleeding 4d before my placebo week. on day 2 of bleeding. should i be concerned?

BCP's: bleeding: Any variation in taking the current "low dose" bcp's can result in bleeding, just as it does at the end of the active pill cycle, during the placebo phase of the pill package. It is unlikely to cause the possibility of pregnancy, as described, but stop the pills now, and resume a new pack in 5-7 days. Take the low dose types within the same time taken the previous day/evening to avoid this.
