Thank you for posting your query.
Your symptoms are non-specific in nature and are not confirmatory of pregnancy. They could be due to urinary tract infection
or any other gastro problem.
You should get an ultrasound
scan of abdomen and consult a gastroenterologist
Urine pregnancy test may be done to exclude pregnancy.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
