Hi, thanks for using healthcare magic
is the most common cause of delayed period, this would be checked with the blood test
you had done.
Other cause of delayed period would be : physical or emotional stress, inadequate diet, excess physical activity, abnormal levels of hormones such as thyroid hormone and prolactin
, PCOS (polycystic ovarian sydrome which is associated with delayed periods, insulin resistance
, abnormal hair growth, difficulty conceiving).
If the test is negative then your doctor may assess any possible reasons for the delay.
I hope this helps
