How effective is birth control after a month of takeing it? 50%, 60%, 80%? any idea? is it up to its 99% yet or no?

After being off it a whole month - 0%. After 3 days it is considered ineffective. Birth control pills are hormones. You take them for just a few days and they start acting on your reproductive system. You miss them one day you need to double up the next day. You miss two days in a row and you need to doublel up for two days. You miss three days in a row - you have to start from scratch. So a month...use condoms until you've been taking them every single day at the same time every day for at least a month.

no i ment how effective is it after you HAVE been taking it for a month

Oops sorry- I read too quick.

There is no one answer - so to be safe consider it 0%.

There are lots of variables....

Do you take it every single day at the same time? (If you do your body will adjust quicker.)

Have you been menstruating for 4 years? (If you have your body's hormones are fully mature and it should take less time.)

Have you had a regular period for at least a year? (If you have that means your hormones are regular and will more easily makes an adjustmemnt that will also be regular.)

Have you been sick and taken any antiobitics? ( Antiobiotics lessen the ability of some birth control pills to work.)

What version are you on? (Some are stronger than others and work quicker.)

I suggest you use two form of birth control for 4 months to be on the safe side if you are a teenager and are willing to risk pregnancy a tiny bit. (If you are oldr 3 months) If you don't want to risk pregancy at all - then always use two because the pill is NEVER 100%.

I have been taking it at the same time for a month
I've been menstrating for well more than 4 years
My period has been regular for more than a year
I've had 2 or 3 bladder infections but not while taking Brith Control
And my body usaly reacts well with medicen

You have to decide how much risk you are willing to take on getting pregnant. Personally if I absolutely positively did not want to get pregnant I would use condoms for 3 months minimally. In theory you should be pretty safe - but theories don't mean anything if you are that tiny per cent that gets pregnant.
