Nausea and vomiting with stomach acid - is it pregnancy?

Patient's question:

Feeling nauseous for several days now, not sure if it's pregnancy

Doctor's answer:

Generally, pregnancy symptoms may appear around weeks 4 to 6 of pregnancy. If you currently have a missed period, experience nausea symptoms, and have had sexual intercourse during your ovulation period without taking contraceptive measures, the chances of pregnancy may increase.
Recommendation:
It is recommended to consult a local doctor for a urine pregnancy test or blood human chorionic gonadotropin (hCG) test for further confirmation. This is because there is a possibility of pregnancy. The specific outcome will depend on the test results. If pregnancy is ruled out, it may be related to a stomach condition.
