<s>[INST] i havent had my periods for more than 2 months now, i was prescribed primolut N 5mg , twice a day for one week, today is the last day to take those pills, yesterday i had unprotected sex. What are my chances of being pregnant? should i take emergency contraceptive pill? [/INST] Hi,Since you did not have a menstrual period during the past two months, you should exclude pregnancy through a pregnancy test and/or a trans-vaginal sonogram. If pregnancy is negative, you can expect withdrawal bleeding 3-7 days after completion of the hormone therapy. As of now, you do not need any emergency contraception since your ovulation status is not established and you are already on a dose of hormones. Please take further advice from your consultant. Once you attain the period, please go ahead with regular form of contraception. Hope this helps. </s>
