Hi GG,
I dont really know what it is doing to your body, just thought I would fill you in quickly on what it did to me.
After I had DD I had implanon in and had it for the full 3 years. I think I had AF 3 or 4 times the whole 3 years. I fell pregnant with DS not long after. After he was born I got implanon again and had a regular AF for 3 months then bleeding every 3 weeks lasting up to 2 weeks. I got it taken out after 6 months because that time it just didnt suit my body.
