Posted on Thu, 17 May 2012
Question: My gf's (age 22) usual MC is 22 nd of every month. After 28th Feb we had sex after which she took unwanted 72 within 3 hours. She again had periods within 14 days i,e 7th March. Since then she did have her periods till date. It has been more than 30 days since then. Pregnancy test on Urine showed negative. Is she Pregnant? Is there any chance she can regain her normal periods schedule from 22nd April? Should we wait till that time before further consultation?

Hello
Welcome,
Your gf's cycle is disrupted due to the emergency pill.The side effect is irregular menses.Nothing can be done about that.If she had her periods in march then she should be due around now..Unless you had unprotected sex in around march 19-24th which would have been her fertile period.If she is delayed and the test is negative then its due to the emergency pill.Just ask her to wait.The cycle will take time to regularise.It would be advisable to use another form of contraception while her periods are irregular.
