Thanks for your query.
Noted the history of missed period but urine pregnancy test is negative.
Wants to know whether this is due to GI Infection?
Yes, GI infection and other causes related to major illness, stress, anxiety, and many factors can affect the dates of the menstrual periods.
Hence do not worry, repeat the test after 5 days.
