[|Human|] hI doc my girlfriend and i had sex on sunday and the condom broke we went straight to the doctor and got a prescription for levonelle and i collected at 9.30 the following morning and my girlfriend took it now she is just panicing that the tablet wont work and what if her period wont come
[|AI|]  Hello, and I hope I can help you today. Levonelle, which is one brand of the morning-after pill, is over 90% effective in preventing pregnancy if taken within 72 hours of unprotected intercourse. So if your girlfriend follow the instructions on the package and took the medication correctly there is a less than 10% chance that she will become pregnant.However, if her period is late, she should do a urine pregnancy test to make sure that everything is okay. It is not unusual for women to have some bleeding 2 to 3 days after taking the morning-after pill. This is not a real menstrual cycle, just evidence that the medication is working. Her real cycle may be delayed as a side effect of the hormones in the medication. I hope that I was able to adequately answer your question today, and that my advice was reassuring. Best wishes and good luck,
