I have a 19 day delayed period, but both blood and urine pregnancy tests are negative. What could be the main reason for this delay, doctor?

A 19 day delay with negative blood and urine pregnancy tests usually rules out pregnancy. The delay may be due to hormonal imbalance, stress, PCOD, thyroid issues, or sudden weight changes. Irregular sleep, travel, or medication changes can also affect your cycle. It is important to get a hormonal workup and pelvic scan to find the cause.

It is happening for the first time that my periods are delayed for 1 week. Urine and blood pregnancy tests are negative. Recently a doctor prescribed me vitamin C tablets and now my new doctor prescribed me methylprogesterone acetate tablets twice a day for 5 days. I took 3 tablets till now but my periods have not come yet. What could be the reason?

My last period lasted 12 days, and now I am 8 days late. I have taken two pregnancy tests, both negative. However, I have been vomiting 9 out of the last 11 days, and certain smells trigger nausea. My periods are usually regular, except for last month and this month. What could be causing these symptoms, and should I take another pregnancy test or see a doctor?

I had a medical abortion in December 2017 and I still have not gotten my periods. I have taken a pregnancy test every month and it has been negative. What should I do and how can I get my periods back?
