wouldnt make sense to do it,as your belly grows the skin around the piercing will stretch and it will be very painful and eventually it will force itself out and i dont think any reputable piercing and tattoo artist would do it knowing your pregnant,just wait till after
If you get it done you have to have time to heal before you get big. Then you take out the bar and replace it with a loop if fishing line. That's the only safe way or it will rip. I recommend waiting till after.
no, most places won't do it either if they know you're pregnant. you could open yourself up to serious infection. Also I got mine pierced about 4yrs before I had my daughter and it's insanely stretched out and can't support most jewelry anymore, it just sags and looks ugly and droopy
