So, the periods were normal up until April 2023, it came on 2nd April. This month had been hectic with fever and exams so medication was taken but not much. The periods were supposed to come on 3rd May based on the cycle but they are delaying and its been 3 days. Pregnancy test kit shows negative results and has been done 4 times . Tried jeera water, turmeric and papaya(unripe) to induce periods but no bleeding occurred. Just some symptoms but no periods occurred. What can be done next.
