Blue around belly button-advice please

[Moomin1000]

Hi
I know this sounds stupid but my belly button is tender and have a blue bruise all around it? Do you think I should be worried I'm 36/40
Thanks for advice xx

I've had this since about 25 weeks (33 now). I think it's just things stretching and baby pressing on bits. Midwife has seen it and didn't seem very concerned, she just said, "Oh, do you keep walking to things then?" It hasn't really caused me any problems since. As far as I know it's nothing to worry about.
