Hi dear, I have gone through your question and understand your concerns.Delayed periods can be due to pregnancy, stress or hormonal disturbances like hypothyroidism
or polycystic ovarian disease
If the repeated urine pregnancy test is negative, then the pregnancy is ruled out.
I suggest you to get your hormonal profile done including thyroid function test, prolactin levels and an ultrasound
done to confirm the diagnosis.
Hope you found the answer helpful.
