Hi I took levonelle a day after having 5 days of unprotected sex. My period then came a week early and only lasted for two and a half days and much lighter than usual (I had no pain, or any symptoms I usually get with my period). I checked the fertility calculator and saw that during the days I had sex they were my most fertile days. My period was due yesterday (ignoring the two and a half day period). Im not sure whats going on.
Hi, If you had regular unprotected intercourse during the fertile days, then you have pretty good chances of being pregnant. A single tablet does not and cannot cover all those days. Yet, the fact that you had some bleeding points to a with Chat Doctor.  I would suggest that you get help if you do not see your period within a week as pills can alter the menstrual cycle by disrupting the hormonal balance. Hope you find this information useful. Take care.
