What happens to a woman who fails the "Law of Jealousies" test in Numbers 5?

God will make her thigh rot and her belly swell.

If thou hast gone aside to another instead of thy husband, and if thou be defiled, and some man have lain with thee beside thine husband:

Then the priest shall charge the woman with an oath of cursing, and the priest shall say unto the woman, The LORD make thee a curse and an oath among thy people, when the LORD doth make thy thigh to rot, and thy belly to swell;

And this water that causeth the curse shall go into thy bowels, to make thy belly to swell, and thy thigh to rot: And the woman shall say, Amen, amen. Numbers 5:20-22
