I am unmarried and have been experiencing irregular periods due to thyroid issues. My gynecologist prescribed Yasmin tablets for 21 days, starting from the 5th day of my period. I have completed the 21 day course today. Could you please advise when I can expect my next menstrual cycle?

After finishing 21 days of Yasmin, your period should start within 3 to 7 days. This is called withdrawal bleeding and is expected. If theres no bleeding after a week, inform your gynec. Thyroid issues can still affect your cycle, so regular monitoring is helpful.

I had dengue right after my last period. Now I got my period 3 ro 4 days late, but it was mostly brown and very light. It lasted only 3 to 4 hours and then I had spotting for 1 day. The pregnancy test is negative. Is this a concern?

Hello, I am a 27 year old unmarried female. I had TB and asthma in December and completed treatment in June. I also received COVID vaccinations. Since then, I have been experiencing lighter periods that start about 5 days before my expected cycle (my cycle is 28 days). After taking ginger, jaggery, turmeric, and milk, my flow becomes normal. I am also taking vitamins and protein powder. Previously, I had no menstrual problems. My recent blood reports are: Bilirubin: 0.6 mg/dl Hemoglobin: 11.3 g/dl RBC: 4.58 million/microlitre Platelets: 325,000/cmm TLC: 7000 Serum protein: 8 g/dl ESR: 45 mm HIV: Non reactive Blood glucose: 91 mg/dl Serum IgE: 61.2 IU/ml Please suggest what could be causing these changes in my menstrual cycle.
