Dear Soft, I would complement you on starting your sexual life. If you had your menses on 6th of this month and are planning to have sexual debut on 31st, mostly it would be safe from pregnancy point of view. Egg is released (ovulation) 14 days prior to next expected menses. Egg has life of 24 hours while sperms are active for 3 days. Hence, a period of about one week around the day of ovulation is considered as fertile window. I shall presume your cycle to be of 30 days. Hence, your day of ovulation would be on 23rd and your fertile window would be from 19th to 27th. So 31st is far away from the fertile window. Hence, you will be having meager possibility of pregnancy due to sexual relations on 31st. However, safe period is one of the most unsafe method of contraception. Hence, I would advise you to take post-coital emergency contraceptive pills. These pills need to be taken ideally immediately but definitely within 72 hours of the unprotected sex. Any sexual intercourse after consuming the pills not protected against the pregnancy. So you can cover this sexual incidence with such post-coital emergency contraceptive pills within 72 hours. If you buy them well in advance, you can take the pills immediately after the intercourse. However, if you are planning to have regular sexual relationship, I would advise you to adopt some regular, routine and reliable contraceptive method like condom, birth control pills or intrauterine device with the advice of your Gynecologist. Use of post-coital contraceptive pills is recommended only for emergency purpose; its routine use is not safe. I hope this provides you sufficient information. Wish you a happy sexual life.
