Unintended pregnancy can happen when contraception is being used

Although unintended pregnancy happens most often when no contraception is used, two studies show that it also happens when it is claimed that contraception is being used.1,2

In fact, over 30% of unintended pregnancies happened when women were using highly effective contraceptive methods like the Pill or IUD.1

It can be calculated that ‘contraceptive interruption’ is inevitable in a woman’s life, where she is trying to prevent pregnancy from the time she is about 17 years old (mean age of first sexual intercourse) until she is about 50. If she is on the Pill she will need to take about 8000 tablets correctly. It is unsurprising that she sometimes forgets tablets or makes mistakes.
