how effective is implanon? (not sure if i spelled it correctly

If u mean the Implant birth control (the little stick thing the insert in your arm), like al birth control it has its pros and cons.

I have the Implant and this is what i've found (be aware this could vary from person to person depending)

Pros:

1. It is inserted into the upper under arm and as soon as it's in u don't have to worry about it
2. it lasts up to 3 years, so no need to remind yourself to take something everyday of visiting the doctor every 3 months
3. Takes little to no time at all to heal, in and out in no time
4. u don't feel a thing and can only feel it inside u if u rub your finger over that specific area with some force
5. Once your first implant is removed your seconde can be inserted at the same time saving time and a lot of hassle

Cons:

1. Is inserted into your arm with a big ezel needle (you do get anasethetic though)
2. Your arm needs to be sliced open to around 1cm in length to remove the implant. (this isn't as bad as it actually sounds, u won't need stitches of anything)
3. u could get slight bruising for a few days after insertion
4. (This doesn't include everyone but i've experienced this and i don't like it too much) Your periods may become erratic. For example, u may bleed meer slighter of heavier then normal of (in my case) have no idea when your periods will arrive due to it not following a calender of pattern. For me i could have a normal period in january but go till April until my volgende one.

All in all it is as effective as any other birth control but it's probably one of the easiest.
