I'm not trying to embarrass you, but you'll need to explore your vagina with your fingers to ensure that you didn't forget. The vaginal canal is dark, moist and a breeding ground for all types of nasty bugs if you don't have the appropriate hygiene. If you can, try to reach all the way up to the cervix to make sure nothing is still hiding. A good position for this is putting one foot up on the toilette and bending over just slightly.
