Nature, in her infinite wisdom must of being having an off day when she dreamed up the female reproductive system. She had so much fun creating the Platypus that she decided to see if she could outdo herself. And she did.
Perhaps she thought that since most women died in childbirth it wasn't necessary to spend much time on their later years. I do wish she'd put a bit more foresight into the process.
This waking up in the middle of night feeling like you've been kissed by flame thrower is the pits.
