Hi

Detailed Answer:
Hi,
Thanks for writing..

I would like to know when was your last periods and is your periods regular?

Plan B has 95 % efficacy if taken within 24 hrs.. So in your case, I feel it would have acted..

Only few women experience the side effects like menstrual change and abdominal distension.. So no need to worry if you have no symptoms after taking the pills.. If in case you have vomited in 2 hrs after consuming the tablet then the tablet has to be repeated..

Hope i have answered your query.. feel free to ask any doubts.. good day..
