No periods. Test negative. Wrong?

Hello,  I had hysteroscopic d&c on August 16 2019 for endometrial polypoidal thickening. Then I got periods on August last week but only spotting. Same with September and October. Last period was Oct 23 with only spotting. Then consulted Ayurvedic doctor.I have used rajapravartinibati tablets for 2 months. as prescribed by doctor but did not get periods. Then doctor suggested susten 100 mg and fol123 for 15 days. From 10th day of course I had spotting for 3 days and was feeling week. After 15 days I did not get periods. Thyroid profile was done and TSH was 5.14. t3 t4 normal. Then after 3 days doctor suggested gestin with fol powder. It's been 5 days I am using those tablets. No periods till now. I had vomiting yesterday. I became very  sensitive to smells. Even smells of flowers make me vomit. I feel like my temperature is little high. I have body Pains. Upt is negative. What is wrong I am concerned. Is there something wrong?
