My husband and I just had to leave the house at 11 pm to purchase Plan B because we had an accident. I am 10 weeks post partum today and decided not to get on birth control because we only got pregnant because we tried. We were in the clear for 3 whole years before getting pregnant. I breast feed and have breast fed these entire 10 weeks. I just read that I don't have to worry about pregnancy for the first 3 months of breast feeding. Was it a smart idea to take the Plan B?
