Can take a while: Medroxyprogesterone acetate injections are a very effective form of birth control. They are effective for 3 months but can have lasting effects up to one year. Confirm with your doctor that it is safe for you to have a 4th c section. The surgeon who did you last one will likely have the most accurate information regarding the amount of scar tissue and the thinning of the lower uterine segment.
