Lump.

I've had this for probably three or four weeks now. I was able to pop it a few weeks ago and all that came out was clear fluid but it never went away and has turned a gray color? It's more or less stayed the same size as when it went down a few weeks ago but it's recently started to hurt if I mess with it but otherwise I forget that it's there because it's only when I mess with it that it hurts and the pain fades away quickly when I do. If I touch it directly it actually feels concaved now. I don't know if it means anything towards this or not but I am 6 weeks pregnant, in case that could have anything to do with it.
