I ended up having surgery when i was 25weeks with my first to remove them. I had the test done at the clinic where they go up the pee hole and see where the stones are lodged. I wouldn't have been able to pass mine so they scheduled surgery.
I'm also 24 weeks and I've passed four stones since I was ten weeks. . Its very painful now I have more and some days I want to cry. My ob is sending me to a urologist but there's not much y can do besides pain meds. Drink a ton of water.. and make sure u pay attention to infection passing them can cause infection in the kidneys
The only thing you really can do is let them pass. but if the pain gets to bad you might have to make a trip to the ER. You have to be very careful about infections when they pass though. i had them and it *****. good luck hun.
