Hi, welcome to HCM.
Renal stone in
pregnancy is complicated to manage. It should be diagnosed on
ultrasonography before treated as
renal calculi. Because there may infrequent uterine contractions which may cause pain. Xrays are not possible in pregnancy.
Also if there is pain on right side , ask your doctor to look for
appendicitis. Ultrasonography is investigation of choice in pregnancy. Take a advise from gynaecologist and surgeon for management of this condition.
Hope I have answered your query.
Regards.
