Should I worry????

This is a skin tag I have on my neck. Does it look like something I should be worried about. I have a couple of them and thus one and one in my armpit are darker in color. I just noticed a mole on my neck above this one as well. I don't know if its new, but I am starting to watch these more. Just wondering if it would be worrisome to you ladies?? Sorry the pictures aren't great.
