Is emergency contraception effective when taken on the third day?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I had protected sex using a condom, and I have PCOS/PMOS. I also took an emergency contraceptive pill on the third day. Given these precautions, what are the chances of pregnancy? I find it difficult to detect pregnancy because my periods are irregular, occurring only once every three months. In the worst-case scenario, if I were to become pregnant, are there any medications available to manage this situation? I am hesitant to inform my parents; please understand. I am currently taking Coercita for my PCOS/PMOS.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern.

You mentioned that you had protected intercourse and that the male partner used a condom, which would have contained the ejaculation. Additionally, you took an emergency contraceptive pill within 72 hours of the sexual encounter. Given these precautions, the chances of pregnancy are low because there was no release of sperm into the reproductive tract, which means fertilization is unlikely.

When was your last menstrual period? To determine your pregnancy status, you can take a urine pregnancy test three weeks after the incident.

Please feel free to reply and follow up if you have any more questions related to this topic.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for your reply.

How can I determine if I was ovulating during the time of intercourse?

I took the contraceptive pill exactly on the 72nd hour. I want to ask the following questions:

  1. How effective will it be, even if it is just five minutes before or after the 72nd hour?

  2. Will there be withdrawal bleeding? When should I expect it, considering I have PCOD/PMOS?

  3. Should I pause my PCOD/PMOS medication for a few days to induce ovulation? I had sex five days ago.

  4. I am experiencing a lot of anxiety and stress regarding an unwanted pregnancy. Am I worrying unnecessarily? I cannot confide in my parents. In the worst-case scenario of pregnancy, are there any pills to control it?

My previous periods occurred earlier, and I am currently anticipating my next one. How serious is my PCOD/PMOS, diagnosed two years ago? Given my weight, height, and BMI of 27, when should I expect my period this time? Will I experience bleeding due to the emergency contraceptive pill?

Kindly help.

Thank you.

Hello,

Welcome back to icliniq.com.

I can understand your concern.

You cannot ascertain whether ovulation coincided with sexual intercourse.

In a female with a normal menstrual cycle, ovulation days can be predicted, during which sexual intercourse should be avoided, or precautions should be taken to prevent pregnancy. Emergency contraception, such as the Ipill, is generally effective when taken within 72 hours. It should be taken as soon as possible.

Withdrawal bleeding usually occurs within a week, but since your menstrual cycle is irregular, it may vary in your case.

Firstly, since you mentioned there was no discharge in the reproductive tract and the sexual intercourse was protected with a condom, why are you so concerned?

For pregnancy to occur, sperm must be released into the reproductive tract, and the female should be in the ovulatory period.

Only under these circumstances can such sexual intercourse result in pregnancy.

If you are very concerned about PCOS/PMOS (polycystic ovarian syndrome/Polyendocrine metabolic ovarian syndrome) and the possibility of pregnancy due to recent intercourse, it is advisable to visit an obstetrician and gynecologist in your area to ease your worries and gain peace of mind.

I hope this information helps.

Please revert in case of further queries.

Thank you.
