I've only just learned that it's actually possible to check your own cervix (evidently should have listened more closely in biology) and as I understand, it's a wildly inaccurate way to check if you're pregnant. I'm interested to know if it's useful combined with other methods and also if anyone else finds something oddly creepy about the fact it can just move about of its own accord? I can't get used to the fact it can just take itself where it pleases! What if it decides to make a break for it and I look down one day and it's on my knee!?
