I've been on the implanon since Nov. '11 lately I been having weird changes to my mind and body. Pregnancy symptoms I'm sure never been pregnant so not 100% sure but cravings moody nausea I haven't missed a period yet its due soon but its always been irregular all I can think of now is being pregnant going crazy over thinking about it what should I do

I've got a question... where do you get these are pregnancy symptoms anyway? Since there are no remotely universal symptoms of pregnancy. Before you state looking like you are something under your sweater anyway.

The point I'm getting at... is if you get it in your head you are pregnant.. you start to see everything as a symptom when its really not.

If you have a doubt... take a HPT and find out. Since no form of birth control outside complete abstinence is 100% effective.
