Did Postinor cause an ectopic pregnancy?

What you need to know:

  • It may also slow the transport of a fertilised egg in the fallopian tubes, hence risking ectopic pregnancy (if the drug fails to prevent pregnancy).

I took Postinor to prevent pregnancy but now I have not had my period for two months. Am I pregnant in the tubes? Kezia

Dear Kezia,

Postinor (levonorgestrel), used as an emergency contraceptive pill, is indeed a synthetic progesterone which works by stopping or delaying the release of a female egg (ovulation). It may also slow the transport of a fertilised egg in the fallopian tubes, hence risking ectopic pregnancy (if the drug fails to prevent pregnancy).

Though some women who get ectopic pregnancies (except for missing periods), may not have any symptoms at first, one can find out whether there is an ectopic pregnancy by doing a simple urine test for the presence of a pregnancy hormone (HCG), a blood test for the same hormone and an ultrasound scan of the lower abdomen through the abdomen or looking at the inside reproductive organs through the vaginal canal (transvaginal ultrasound scan).

Later on, an ectopic pregnancy may cause serious lower abdominal pain, bleeding from the uterus and symptoms of the ectopic pregnancy bursting such as feeling weak among other symptoms.

Postinor prevents pregnancies and its failure rate is low, which means it should be trusted to prevent pregnancies, including ectopic ones, which it is said to risk causing.
