I had one, I took mine out. Although it wasnt due to pregnancy. I just had a dream I took it across the back of my teeth and my teeth disintegrated lol it was so scary I freaked out n took it out. My tongue feels SOOOO much better though! And I loved my tongue ring, but ooh well! (: its basically your choice. You don't have to though!
I still have mine in…this is my second pregnancy…the nurse made me take it out for an epidural when I had my first daughter
I kept mine in, usually they only require it to be taken out for a general, not sure about epidural though, I wouldnt think so though
I didnt ive kept it in thru both my pregnancy if u get n epidural tho they might hav yu take it out for precaution
