IUD kind of scared?!

Tamsin • 16 :)
Is it normal to be worried about getting this done? I've been wanting it for some time so I no longer have to worry about taking the pill, but I'm scared of having someone looking right at my vagina?! I'm also worried that something will prevent it from working when I get it done and that it will get lost in my body? Am I worrying too much for no reason?
