Thanks for posting your query.
With the available described symptoms, there appears to be possibility of peptic ulcer disease
with decreased gastrointestinal motility and reflux of acid in food pipe.
Megapen contains Amoxycillin
and its an antibiotic and will not help in your case if it is used alone.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for complete blood count
, thyroid profile, blood sugar, serum electrolytes.
You should also go for urea breathe test for H. pylori bacteria' a culprit agent for peptic ulcer disease.
Your condition also need endoscopy but with history of pregnancy
, this can be avoided.
Meanwhile, you should take proton pump
inhibitors along with prokinetics.
You should avoid tomatoes, citrus fruits. tea, coffee, oily and spicy food.
