I had to for my csection, all jewelry removed
No u don't I took mine out just because the inflamation from my boobs getting bigger was making them hurt really bad. If you do plan to breast feed you have to take them out when u feed and make sure you clean them with a anti bacterial soap or cleaner after to prevent infection think of it this way someone will be salavating on them all the time so that can be an issue. I recomend you go buy the plastic or silicone bars that are alittle longer that helped me with the streching and if you go to the doctors or hospital they usually don't make you take them out if there not metal
Not necessarily. only unless you plan to breastfeed. Thats what I think at least.
