Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You are 33 weeks pregnant, had pain in the right side of the stomach, It comes suddenly and remain for few minutes.
it is your 2 nd pregnancy
, and the first was C section. You had all sorts of pains,but this is different.
After 32 weeks of pregnancy the fundus of the uterus
enters the upper part of stomach, and stomach and other parts of the abdomen has to be adjusted accordingly, till it is accomodated, and uterus get anti verted position, and stomach is lacking space for its movements.
Some of these facts may cause stomach pain. other causes are pressure on the parts lying on the right side of stomach.
Though the problem is not unbearable, it is always better to consult a doctor for diagnosis, for healthy maintenance of the pregnancy.
Wishing for a quick and complete recovery.
