"i&#039;m writing this to calm the nerves of the constant internet searches during this uncertainty period between taking plan b and waiting for your period. i had sex a day before my ovulation day, the condom broke and we didn&#039;t realize till he finished. i started freaking out since i knew that plan b worked by delaying ovulation, though my calendar said i would ovulate the next day it wasn&#039;t 100% certain that i was already ovulating or finished ovulating. i took plan b an hour after intercourse and asked the pharmacists if it would work during ovulation and the pharmacist told me that it is recommended at any time of the cycle. i experienced headache, bloating, nausea, breast tenderness/swelling and pre ovulation discharge till i got my period!"
