welcome to HealthcareMagic
Lenovelle is a emergency contraceptive pill
and has to be used with caution and since it is a hormonal
pill it can disturb your periods so it should not be used more than once a month.If you are sexually active and have more than once in a month then you should start using the regular birthcontrol
pill which will help you avoid pregnancy
as well as maintain your periods regular.Now for the main question and the answer is No Levonelle
will not make you infertile as it is a hormonal pill and the effect will wear off after the periods come but it can disturb your periods so use only when necessary and as advised.Don't worry.
