I haven't taken a test yet...
Hi there,
Your pregnancy test is negative so other causes of delayed periods like thyroid disorders, hormonal fluctuations, PID and ovulation dysfunction should be considered. You may need additional tests like ultrasound scan of pelvis, hormonal assay etc. Semen analysis of our husband may be helpful. This is merely an advice and not a substitute for clinical examination .Consult your gynecologist for more queries and assistance. Keep me posted.
Best luck and take care!
