Periods Problem. I am really exhausted.

Hello Doctor, I am Anakana and i have been suffering from periods problem for 1 month. Usually i have 27-28 days cycle and that lasts upto 6 days. But in March i got my periods on 7th March which is 22nd day of my cycle and it lasted for 7 days with heavy bleeding. But after that I again got periods on 23rd march which lasted for 6 days with normal flow. Again today that means 1st April i got my periods. I feel pain in my lower abdomen.I also have nausea. I don't feel hungry and only can eat small portions. After that i feel really full. Also i had lost 6kgs but I am not sure if it is because of this problem. I have been working out for last 5 months. I am not pregnant. But i have PCOS. I never felt these things before. I can't consult any doctor face to face due to this corona situation. Kindly tell me what to do. I am really exhausted. Thank you.
