It all felt the same to me. Insertion felt crampy (highly so) and afterward felt crampy (highly so).

Huh. Dilation wasn't something I'd have labeled crampy (seems far too mild a term)... apparently my body DOES NOT LIKE having my cervix dilated. Fascinating. Of course, the fact that I seem to recall your body already misbehaving in that particular area may simply mean that you were more used to it. Or something!

I suspect that, of the options, it's precisely best. (since they won't let me get sterilized yet)
