Periods issue. There is no sign of it.

I am unmarried girl of 24 years. I had my last period on 21 January. On 26th Feb I had 2-3 drops of bleeding. Then again in March 25th I had bleeding of few drops only. I didn't had any issue related to periods before, as they were normal and timely. I consulted a doctor and she suggested me to get hormonal tests, urine pregnancy test, blood tests and ultrasound done. All my reports came out to be normal. UPT is negative, Pelvic ultrasound showed right ovary PCOD configuration. FSH is 5.18mIU/ml, LH is 12.4 mIU/ml, prolactin is 9.8ng/ml. TSH is 0.595uIU/ml. Doctor prescribed me Yasmin (drospirenone and ethinylestradiol tablets). I took them timely for 21 days and now after taking them today is 5 th day and my next cycle of medication will start in 2 days. I still haven't got my periods. Because of covid I can't visit any hospital. Kindly suggest what should I do in this case. She told me after taking hormonal pills for 21 days I will get my periods for sure but there is no sign of it.
