Hi everyone,

I'm into my 3rd year of my Implanon contraceptive implant and so far have had no problems at all.

When I had it inserted I was overweight, but in the last two years have put on even more weight...and I've read quite a bit on the net that the Implanon can become less effective after 2 years if you are overweight.

The last couple of weeks I have been feeling tired with nausea and headaches, and also heartburn...which I know are all common signs of pregnancy.

Has anyone heard of anyone falling pregnant whilst using Implanon, or heard of anything about it becoming less effective if you are overweight?? I know it's a very reliable method of contraception and the odds are I'm not pregnant, but I would be very grateful for any imput you may have??

Thanks, Kat xx

Hey miss Kat,
There is a suspicion that the implanon may lose some of its power in the last 6 months if you have a BMI of over 35. It is not proven and the implanon instructions say 3 years for everyone. Some family planning clinics say to change them at 2 and a half years to be 100% safe. If you are in the last 6 months of your implant and overweight I would do a test to be safe and maybe get alone to your family planning clinic to ask their advice about an early change.
Good luck xxx

Sorry, confused, if you are in your third year does that mean you have a new one in? If so then you shouldn't have any probs.
