thanks for choosing healthcare magic
All the symptoms that you have mentioned are very commonly seen in cases of ulcer .
Kindly take all the medications prescribed to you regularly and also consume bland and non spicy food as advised to you by your doc
these symptoms are definitely not suggestive of pregnancy
. you should consider pregnancy only if you had unprotected sexual intercourse and if you have missed your periods.
if you have had your periodsnthen you can easily rule out pregnancy , if not then you can get a urine pregnanct test done at home
