Thanks for your query.
If you had your expected date of period on 29th , there is nothing to be confused, because the expected date would be 1st of March.
If you have irregular periods
, you cannot rely on simple home pregnancy
tests as you might have irregular ovulation also.
The symptoms you describe are non specific actually.
You could be having pre menstrual symptoms.
pain in the pelvis with difficulty in urination occur in pelvic infections also.
To know if you are pregnant, and to rule out infection, please consult your gynecologist.
