Can you get pregnant on testosterone and if you don’t have a period?
If you're trans or non-binary and taking testosterone therapy, it might reduce your fertility. But it doesn’t provide adequate contraceptive protection, so you'll need to consider additional contraceptive methods in order to prevent pregnancy. There is still a risk of pregnancy, even if your periods are irregular or you are not having periods.
Methods you might want to consider include progestogen only contraceptives, such as the progestogen only pill, injection or implant, or a hormonal or non-hormonal coil.
It’s important to be aware that there are risks to the baby if someone taking testosterone were to become pregnant.
