I have four on my stomach and almost 25 weeks my piercer said leave them be unless they start to reject on their own my drs are not thrilled but I'm trusting my piercer on this one. Mine are not even close to rejecting on their own so I'm just waiting it out!
I have 5 on my chest and I'm keeping mine :)
I have a skin diver in my hip , I had one on each hip but one got caught in my sleep and came out, im chancing it and just leaving it in, I would have to go and get it cut out but that scares me :p
I have hip dermals, I believe I have to take those out when I get farther along :/
I don't have dermals but I have almost twenty piercings. I'm not planning on taking anything out. All of it is surgical steel. I would ask your doctor for his advice or leave them in and if they become uncomfortable at some point then take them out.
