Naval piercing: in or out??

I've had my belly button pierced since I was 16, I'm 30 now, and I don't want to take it out just because I'm pregnant. Reason one is that it's not constantly bothering me, some twinges of pain/stretching here and there but nothing unbearable. I have a flexible ring in now and seems to be fine so far. I'm 1 day shy of 17 weeks pregnant. Reason two is IF I take it out now, getting it pierced again post delivery is weird to me. To me it's weirder to be 31+ going to the parlor for a naval piercing than it would be to have never taken it out and still have it into my 30's. Thoughts?
