Birth control options.

I used to have an iud before my first pregnancy. My second child is 10 months old but I really don't know if we want more children or not and I know that I wud not want to wait five more years. The pills make me sick. I tried the ring and hates it. I really don't want the shots cause I have heard they can cause weight gain. Had also heard bad things bout the patch. Any other ideas?
