I had unprotected sex with my girlfriend on last month 27. Till now she did not have her periods (mensuration) came. After sex she took an I pill tab. And mostly on every month her mensuration date on last of every month. Are we in safe zone doctor? Is there any need of pregnancy check up required?

Thank you for your question. Taking the ipill is associated with the side effects such as abdominal pain, unscheduled bleeding, bloating, period like discomfort, early or late periods and also of course a pregnancy. If she took the ipill within 24 hours of unprotected intercourse you are 95% sure to avoid a pregnancy. Any later and the success rate also reduces. I would suggest that you wait for her period to come. If it is delayed by over 7 days to do a pregnancy test. I would also suggest that you see your local gynaecologist to discuss other reliable methods of contraception if you will be having sex regularly. Ipill is an emergency contraceptive and should only be used for emergencies when your regular contraceptive fails. It is important to know that there is really no such thing as a safe period in young fertile women. Even if you are using condoms consistently and correctly you will have a failure rate of about 15 %. Unprotected intercourse has a 40% risk of unwanted pregnancy in any part of the cycle greater when it is midcycle. Please seek advice regarding more reliable contraception if you do not wish to have a baby just yet. Best wishes.
