The morning after pill isn't the type of thing you want to use on a regular basis. You go and get two pills, one to be taken 12 hours after the first. Then in about 3-4 days a period is induced.
They have been known to fail but now the success rate is up to 99.7%. However this is not a BIRTH CONTROL method. It is EMERGENCY CONTRACEPTION. So no it's not better to do it this way. The hormones come in extremely high dosages with the morning after pill and are also about 15 dollars per pill - dangerous and expensive.
Been ages since this thread was active, but I'm bumping it to see if anyone bites. There's a growing group of women (not necessarily body builders, just fed up with hormonal pills!) using this pill, two online "clubs" and a very active discussion on the Contraception forum of www.aphroditewomenshealth.com. Anyone on this forum still using it? We'd love more input from users!
