Hi.
Thanks for your query.
Noted the history and understood your concerns.
Unprotected sex with
irregular periods and negative
pregnancy test may not be related to being gassy and burping with growling stomach.
I would advise you to take a PPI like
Omeprazole and an antacid liquid every three hours and see the results.
If this does not solve your problem please consult your Doctor for clinical evaluation, examination and investigations like
Ultrasonography of abdomen , tests blood and stool.
Repeat the pregnancy test after 5 days to ascertain.
Further treatment will be as per the findings.
You may need further treatment with
Domperidone to stop burping otherwise GERD like problem may start. Antibiotic if thee is an intestinal infection as indicated by gurgling stomach and gases. Activated charcoal helps further.
Take boiled and cooled water and home-made food only.
Avoid foods and beverages that enhance the problems.
