And, FWIW, the immense amount of pressure "down there" has caused me to have something like a blood blister(I think they call it thrombosis) on my labia in two of my pregnancies. Not fun - but they do go away post partum - is that what the skin tag is?
A skin tag is just a benign tumor, an overgrowth of squamous skin cells that hangs off your skin like a floppy little tag. It's soft and normal feeling--not rough or weirdly rubbery like a mole. It feels like normal skin that just really shouldn't be there. Some people say you can pinch them off, tie them off and let them fall off and die, or cut them off with nail clippers or scissors. I'm a home remedies kind of girl and would totally consider doing one of those if the skin tag weren't, you know, ON MY LABIUM. Think I'll ask the midwives to take care of it, or recommend someone who can.
Pregnancy is so glamorous!
