Advice please!!!

Hey everyone, I need some advice!! I woke up 2 days ago with a horrible sharp pain in my right side, went to work but ended up getting sent to my doctors and then into the hospital to make sure everything was alright. It's a really sharp stinging pain on my lower right side that hasn't gone away, I had bloods done and all that and the doctors said it could be stretching pain but they can't rule out that it's not my appendix because I never got them out 😭 freaking out because I really hope it's not my appendix. I still have the pain, its not as severe and comes and goes. It's when I try to straighten up or when walking or turning certain ways... Anyone any idea what it could be. Praying it's nothing serious. Also had my big scan yesterday at 22+2 and baby is all good thank god!! Any advice is much appreciated!! :) x
