How Well Do You Know Your Way Around Your Uterus?
Hint: probably not that well.
You might have a uterus, but how much do you really know about what's going on with it? And if you don't have one yourself, we're guessing you probably know even less about their deal.
No need to sweat about it though as we're at your cervix with a handy test to sort the ovaries from the uterine walls and perhaps teach you a few things about the female reproductive system while we're at it...
