Hi, I understand your query. Abdominal pain in pregnancy 28 weeks can be due to causes- * pain associated with uterine contractions needs immediate attaintion- as it might be pertaining to fetal health. You are already taking progesteron pills, add uterine relaxants like Duvadelan twice a day/ take rest--- and plan to visit your gynac for further examination & advise. * Gastrointestinal upsets in pregnancy many a times lead to Gastritis, regurgitation, hyper acidity/ indigestion, dyspepsia,constipation. Such cases need management by altering eating habits, antacids,proton pump inhibitors,digestive enzymes as per need Drotin is an antispasmodic drug though useful in controlling colic, may cause slowing down of intestinal movements- and cause further digestive upset. It s use needs to be decided after your doctor evaluates the cause. Thanks.
