Hello dear,
I understand your concern.
In my opinion the unwanted 72 comes under emergency
contraception.
The emergency contraception is used when the protection is failed like irregular intake of birth control pills or tear or slippage of condom etc.
But it should not be used for regular usage.
Unwanted 72 is high dose
progesterone hormone.It causes
hormonal imbalance.
So if used regularly it might cause heavy bleeding.
So restrict for emergency situations.
Unwanted 72 is effective in 95% cases in preventing
pregnancy if taken within 72 hours of
unprotected intercourse.
Intercourse can be done without protection in case of safe period of menstrual cycle.
Safe period is the one where there are no chances of pregnancy with unprotected intercourse.
Safe period is said to be roughly around 1 week before and after the period and during the period.
But this safe period method or natural method is applicable only in case of regular cycle.
So kindly check for the safe period and if inevitable you can go for unwanted 72.
Hope this helps.
Best regards....Dr.Srilatha
