Choosing between 1-month and 3-month injections
The two options work differently and suit different situations. The doctor can explain which may suit you based on your health history, side-effect preferences, and how soon you would like fertility to return after stopping.
What the doctor reviews before your first injection
- Timing since your last menstrual period
- Breastfeeding status, if relevant
- Blood pressure and relevant medical history (e.g. migraines, blood clot risk, liver disease)
- Current medicines and any known allergies
Side effects and what to expect
Both injection types can affect your monthly bleeding pattern, and some patients notice other side effects such as mood or weight changes. The doctor will explain what to expect and when to come back for your next dose.
Important to know
Contraceptive injections do not protect against HIV, syphilis, or other sexually transmitted infections. If you may also need STI protection or testing, mention this to the doctor — condoms remain necessary for STI prevention alongside any contraceptive method.
Frequently asked questions
What's the difference between the 1-month and 3-month injection?
The 1-month injection combines two hormones and is given monthly. The 3-month injection contains a progestogen-only hormone and lasts longer between doses. The doctor can help you decide which suits your health history and preferences.
Do I need a blood test before starting?
Not always — this depends on your medical history. The doctor will advise if any tests are needed based on your health background.
Does the contraceptive injection protect against STIs?
No. Contraceptive injections prevent pregnancy only. Condoms are still needed for protection against HIV and other STIs.
Can I start the injection at any time in my cycle?
Timing affects how soon the injection becomes fully effective. The doctor will confirm the right timing based on your last menstrual period and discuss whether additional contraception is needed in the first days.
