I have skin tags as well since bein' prego. They're ugly and annoying! I had one down there on my va jay jay then It went away but a week later I got one on my butt and that one Is still there. Ugh! I also have two on my neck and one on my left nipple. I heard they go away after delivery and I really do hope that's true!
It's actually very common to get skin tags, anywhere, during pregnancy. I'm really not sure if they go away or stop after delivery, maybe talk to your OB about it?
