"i got the implanon in october 2009 three weeks after giving birth to my second son. at first i did get anxiety pretty bad but it went away quickly. my periods pretty much stopped. every once in a while i will get a normal period. but for the last month and a half i have been having horrible headaches, no sex drive, mood swings but worst of all i have been having random pains all over my body. my doctor says its neurological. i have had an mri ultrasound and all kinds of blood work.
