From her own personal experience, Michaela Deane describes the process of using the implanon, otherwise know as "the bar", as a form of birth control.
The Implanon is a flexible rod, also known as “the bar” that’s inserted into your arm to prevent pregnancy. It lasts for three years and works by releasing progestin, which stops an egg being released from your ovaries. 
Although no birth control is 100% effective, the Implanon has a low failure rate, with less than 1 out of 100 women a year becoming pregnant while using it. 
You don’t have to worry about taking it every day, every week, or every three months, and it can be removed whenever you want. So why is it so uncommon?
I think the number one thing preventing girls from trying this method of birth control is the procedure of having the bar inserted. 
It’s done by injecting a needle into your arm which places the 4cm rod under the skin, and even as a girl who’s had her fair share of piercings done, I was petrified of the procedure. And I was shocked when it was over, because I didn’t feel a thing.
The doctor first injects you with a local anesthetic to numb the area, and I mean it when I say you’re completely numbed. The injection is the only part of the procedure that hurts, and it’s only a sting. 
After that, the Implanon is injected into your arm, it takes all of 30 seconds and you honestly can’t feel any pain. Your arm is a little tender and bruised for a day or two afterwards, but that’s nothing a paracetamol can’t fix. 
Another thing that can put girls off getting the Implanon is the fear of getting a constant period, or irregular spotting for a while. This is the side effect that put me off getting it done for months, even though there was the chance that it might not even happen. 
However after talking to a nurse, she informed me that if this happens you can be put on the pill for a month to regulate the bleeding, and after that it should be fine. 
Because of this potential side-effect, I’d recommend getting the Implanon when you’re not sexually active. Remember that all methods of birth control have side-effects, and you may not even experience any.
Now, it doesn’t seem so bad after all, does it? If you’re worried about grueling side-effects or the pain of having it inserted, hopefully this article will have eased your mind a little bit. 
You never know until you try it, and this could be the method of birth control that suits you best if you give it a chance. 
However, remember that no form of birth control is 100% effective and the only thing that will protect you from STI’s is by using a condom.
