how many months does it take to get birth control out of your system
Best Answer: Others are correct about the 3 months. However - not the full truth. Hormones, such as birth control, or hormone replacement therapies, take about 3 months to build up to proper levels in your circulatory system. This is why its not considered quite effective for 3 months. As such, it takes about 3 months for it all to leave your system, and go back to your normal levels.
