Question: I got the birth control shot, why is it important to get the shot with in 6days of the 1st day of your period?
Because otherwise you might ovulate before you get the shot. If you wait a week after your period starts, it's possible you've already ovulated. Then the shot won't prevent ovulation. Then you'll think you're protected, won't use a condom, and then will get pregnant anyway because the egg was released before you got the shot.
not 100% sure, but i think its so it doesnt mess up the pattern of your peroid? Could be completely wrong though!
