I have time tonight. I have been bombanded with questions on Postinor 2 on every side for the last one month and I have decided to answer all your questions on morning after pills. There are also plenty of Postinor myths circulating around both the print media, social media and our everyday conversations and I want to dispel them tonight.

I have compiled over 30 frequently asked questions on levonorgestrel (Postinor) and I am going to answer them straight away using headers.

1. Does Postinor 2 cause cancer?

No. There has not been a report or research that shows Postinor to be a cause of cancer in women. However is is recommended that those with any form of cancer such as breast, ovarian or cervical cancer should not take the morning afternoon pills.

2. What are the side effects of Postinor 2 on menstruation?

Postinor do have some effects on your menstrual cycle. It works by delaying ovulation and thickening of the cervical mucus preventing spermatozoa from getting to the Fallopian tubes. Postinor 2 may delay your flow by some days but not later than 5 days. If after taking your morning after pill, your period delays by 5 days or more; please see a doctor for a pregnancy test.

3. Can Postinor 2 cause infertility?

Emergency contraceptive pills do not cause infertility. There are many things that causes infertility in women and postinor is not one of them. Levonorgestrel has not been reported to cause infertility. It is a myth that has been dispelled.

4. Can I take Postinor twice a week?

I don’t think it is advisable. It is an emergency contraceptive and not meant to be abused. Taking postinor twice a week amounts to abuse and it has its consequences. Do not take Postinor more than twice in a month. If you are a very sexually active person, I advise you go for a longer term contraception like IUCD or implants.

Just like other hormonal contraceptives,levonorgestrel(Postinor) reducing your chances of developing uterine fibroids, breast cancer, and ovarian cancer. This does not mean you should use it as a long term contraception.

7. Can taking morning after pills too many times cause infertility?

No. But you should not be using postinor routinely or as a long term contraceptive plan. If you know you have intercourse quite often please go and insert an IUD or implant. Taking postinor too many times will cause you weight gain and serious menstrual problems that may in some way affect your ability to get pregnant. Don’t abuse it.

8. How long does morning after pill delay ovulation

How many days will Postinor 2 delay period?

You are not likely to get a specific answer here because it varies from woman-to-woman. Your next menstrual period is likely to arrive on time. However, it may be slightly early or late. If it is more than 1 week late, or if it is unusually light, perform a pregnancy test. If you do not have a menstrual period after 3 weeks of taking postinor-2, you may be pregnant.
