Contraceptive injection how long does it last

However, there can be quite a delay before a woman is back to the level of fertility that she had before starting on the injections. Figures vary from three to six months but they depend on how long a woman has regularly had the injections. Fertility not only depends on whether you are producing an egg or not, but also how regular your periods are — that is, how many eggs you produce a year.

To put everything into perspective: no matter what sort of contraceptive couples were using, the vast majority would have become pregnant by the end of a year of trying. This is why doctors do not usually worry about such things until after this time, as they know that by this stage, most women who want to get pregnant will have done so.

I'm not sure why you were told a year ago that you were very fertile as at that time you would have still been on the Depo-Provera injection, but I suspect what was meant was that you are at the most fertile period of your life which is usually quoted as the late teens to early twenties.

You will need to return to the clinic to have the Depo injected. It will be cheaper if you have a healthcare card. If you do not want to become pregnant and it is more than 14 weeks since your last injection, you can abstain from sex or use condoms until you can have your next injection. It can take up to 7 days for Depo to start working to prevent pregnancy.

During this time, you can continue to abstain from sex or use condoms. If you have unprotected sex in the time when your Depo is late or not effective, you might need emergency contraception. The injection is not known to harm a pregnancy.

It is safe to continue the pregnancy or to have an abortion. Generally, the injection can be administered straight after you give birth, even if you are breastfeeding.
