Brief Answer: Wait for pregnancy test Detailed Answer: Hi again Since the sexual intercourse date is on 18th day of the menstrual cycle, the chances of pregnancy are there. Taking I-pill is protective. I think she may have delayed period due to stress. Still we need to rule out pregnancy with a pregnancy test. The pregnancy test can be taken around 4 - 5 days after missed periods to be sure. Before this time it may be mildly positive or falsely negative (if pregnancy is there). Thus it is better to wait for 4 - 5 days and then do the pregnancy test. You can discuss the report with me or with your doctor. Hope it helps. Dr Vaishalee

Brief Answer: Two options after 4 - 5 days Detailed Answer: Hi again After 4 days, take pregnancy test. Next management depends on the report of pregnancy test. If the test is negative, that is no pregnancy, then she can take a 5 day course of progesterone hormone under supervision of a gynecologist. It will result in withdrawal bleed, that is periods. If the test is positive, then it is your choice whether to have the baby or not. If not then there are medicines available that can result in abortion. These medicines are also better taken under supervision of a gynecologist. In any case there should not be any worry. Take care Dr Vaishalee
