Not sure what group to post this in…

I’m 20 weeks pregnant and about 3 days ago I switched my normal belly button ring to this pregnancy ring. Soon after I did this it started to get red and hurt. The pain isn’t excruciating or anything and it doesn’t hurt all the time it basically just feels sore sometimes especially if anything touches it. I got my belly button pierced 4 years ago so it’s completely healed and there’s no puss, it doesn’t hurt to move the bar up and down, and it doesn’t look infected to me…

I’m just wondering if the redness and discomfort is being caused by my belly growing and stretching the piercing or if I should just take it out… if I leave it in will I eventually get used to it?

Sorry for long post and thanks in advance
