Which birth control causes the most counterbalance gain?

And by the way, guys don't answer. This isn't your department. I lately had a child and WANT TO GAIN WEIGHT. I do not want to lose. Which birth control will make me gain alot of immensity? Depo Provera is dangerous, I wouldn't rob it. But I am considering Mirena or Norplant because my husband and I don't want another child for at least 2-3 years. Mirena is expensive for the 5 years it works. But I've be on the patch and pills and they made me moody and I couldn't remember to take the pills. I don't close to Ortho's products, either. So what do you recommend? I'm considering and IUS or IUD.

My doctor say I have a thyroid problem, what are my option for treatment? What should I be prepared for?

Depo, but like you said DON'T TAKE IT.

Consult next to your doctor about your option.

Period problems?

Same as above, Depo injection is a weight gain wannabes bliss.
Speak to your GP about it, further as they may explain what contraception suits you best.
Why don't you devour more fatty foods if you want weight gain?
