Wow Saragirl, it sounds like it's time for another doctor. I'd be sorely tempted to call your doctor and give him a peice of my mind if I were you. I mean, what if you weren't as intelligent and educated as your are, took his word instead of questioning and wound up pregnant again? That would be awful, I wonder how many other people he's spreading misinformatino to.
When you sayimplat do you mean the norplant (that's the one in the arm right?) or an IUD? Some IUD's are not hormonal, are easy insert (especially after you havea child) and carry very little risk. I beleive the only real risks are expulsion and a tiny chance of a perforated uterus and infection.
I'm pretty ignorant about the arm implant, but if it's hormonal BC it's probably not great for breastfeeding moms.
