Found this in my girls arm still trying to figure out what it is

Contraceptive implant
The contraceptive implant (Nexplanon) is a small flexible plastic rod.

If implanted correctly, it’s more than 99% effective. Fewer than 1 in 1,000 people who use the implant as contraception for 3 years will get pregnant.

It’s placed under the skin of your upper arm by a doctor or nurse to prevent pregnancy. It does not protect you against sexually transmitted infections (STIs).

How the implant works
The implant prevents pregnancy by releasing progestogen which:

prevents you from releasing an egg (ovulating)
makes it difficult for sperm to get to an egg
thins the womb lining, so there’s less chance an egg will attach to it
When it starts to work
You can have the implant put in at any time during your menstrual cycle, as long as you’re not pregnant.

If it’s put in during the first 5 days of your cycle, you’ll be protected against pregnancy.

If it’s put in on any other day of your menstrual cycle, you should use additional contraception such as condoms for 7 days.

After giving birth
You can have the contraceptive implant fitted any time after you’ve given birth.

If it’s fitted on or before day 21 after the birth, you’ll be protected against pregnancy.

If it’s fitted after day 21, you’ll need to use additional contraception such as condoms for 7 days.

It’s safe to use the implant while you are breastfeeding.

After a miscarriage or abortion
The implant can be fitted immediately after a miscarriage or an abortion. You’ll be protected against pregnancy straight away.

How is the contraceptive implant fitted or removed?
Local anaesthetic is used to numb the area on the inside of your upper arm.

The implant is inserted under your skin. It only takes a few minutes to put in and feels like you’re having an injection. You don’t need stitches after having your implant fitted.

It works for 3 years before it needs to be replaced. You can use the contraceptive implant until you reach the menopause.

The implant can be removed at any time by a doctor or nurse. It only takes a few minutes to remove and local anaesthetic will be used. Your doctor or nurse will make a small cut in your skin to pull the implant out.

Once your contraceptive implant has been removed, you’ll no longer be protected against pregnancy.

Your implant is usually removed by the service or practice where it was fitted. If this is not the case, your GP or sexual health service can tell you where implant removal is provided in your area.

Who can use the implant?
Most women can use the contraceptive implant, however it might not be suitable for some people. Your doctor or nurse will talk about this with you.

You should not use the implant if you:

do not want your periods to change
take other medicines that may affect the implant
have unexplained bleeding in between periods or after sex
have severe liver disease
have breast cancer or have had it in the past
have a medical condition that may affect which contraception you can use – talk to your doctor or nurse about this
What if I’m taking other medicines?
Some medicines can stop the implant from working.

These include:

medication for HIV
medication for epilepsy
complementary remedies, such as St John’s Wort
some antibiotics, such as rifabutin or rifampicin
If you’re taking any of these medicines, you’ll need additional contraception. You may wish to change your form of contraception to one that isn’t affected by your medication.

Always tell your doctor that you’re using an implant if you’re prescribed any medicine.

Side effects of the contraceptive implant
The contraceptive implant may cause side effects. You should consider these carefully before deciding if it’s right for you.

Disrupted periods
Your periods may change significantly while using a contraceptive implant. Around 20% of people using the implant will have no bleeding, but almost 50% will have infrequent or prolonged bleeding. Bleeding patterns often remain irregular.
