I am 20 years old. I took Covid vaccine (Covishield) on 24th June, 2021. It caused me fever and body aches along with prolonged weakness. My stipulated date for the periods in June was 28th to 30th June only but now it's 16th July and my periods have not yet arrived. I am highly stressed out. I experienced white discharge around 6-7th July and then it stopped around 10-11th July. Since then I am experiencing pre-menstrual cramps but they are also irregular unlike before. The white discharge has started again since yesterday. There is a slight discomfort as well. Please let me know if this is due to the vaccine only or is there anything else as well? Pregnancy cannot be a factor with me so please help me out what can it be? I would be highly grateful to you. Please
