I take it, skips periods it's great
Pills
I still take pills, despite the belt.
BD1791 Abstinence is the best way of preventing unwanted pregnancy.
But it's the way with the highest risk of failing, how good abstinence is working you can see on teenagers in US high schools where they teach abstinence as the bed solution.
BD1791 That means understanding the risk and deciding for yourself if it's a risk you want to take.
That's what I say. The girls should make an educated decision themselves. Not the parents.

Sara2001 Yes, we absolutely agree in this point. I think the way with the highest risk of failing can't be the best way.
I wonder how much the teen pregnancy rate would fall in the US if teens were belted. I'm sure substantially 
Also, most parts of the US does not have comprehensive sex educated. We don't even teach about condoms. It's a real problem.
The most we have used is condom.It seems that she doesn't like it.So sometimes we used pills too.We have not find side effects now,though the instructions say they may have some side effects.
I think it's very important to control the total dosage to avoid side effects.
Sara2001 think the average time woman take them is far higher then 3 years
And it implies certain risk. In 2017, a large Danish prospective study reported breast cancer risks associated with newer formulations of oral contraceptives.
Women who have used oral contraceptives for 5 years or more have a higher risk of cervical cancer than women who have never used oral contraceptives. The longer a woman uses oral contraceptives, the greater her risk of cervical cancer increases. One study found a 10% increased risk for less than 5 years of use; a 60% increased risk for 5 to 9 years of use, and twice the risk for 10 or more years of use.

Of course, these are studies, but the most important thing is what each girl tells her doctor, who is the one who can best assess different markers in analytics.
(Moved answer from other thread (see https://unwedchastity.org/d/40-breaks-for-masturbation/591 ) to the one at-hand, since it seem to be more on-topic here.)
Sara2001 Or using preservatives or the anti baby pill, like round about a billion woman in the last 50 years.
Know what you mean, yet those mentioned usually require ongoing, conscious actions, which some do not manage or are unwilling to take. Not to speak of "adverse sexual 'partners'". In this regard, consequences of errors and 'bad outcomes' can just be extremely serious.
I know cases where people regret to have bet on preservatives and pills.
