TMI!!! What is this?!

I'm so so sorry to be posting this but I'm really nervous and its night time and the weekend so I can't get into my gyn- I noticed in the shower when I was washing my lady party a small lump on my inner vagina that feels sort of like a little skin tag, I just started working out, and am 30 weeks pregnant so i sweat a LOT down there anyway I had my husband scope it out and take a picture only to see its PURPLE!! Now I'm really freaked out, what the hell is it?! It's painless but still not normal, anybody ever have this?
