###Human: Why am I having delayed periods with hot flushes, dizziness and fever? ###Assistant: Hello. According to your history and symptoms, it seems that nothing is wrong with your body system. Sometimes, periods get disturbed. Your symptoms are pointing towards signs of PMS and I feel that you are panicked by the situation which is making the condition worse. I would suggest that you have not to worry about it and just wait for a few more days. Hopefully, your cycle would resume by itself because unrecognized stress results in delaying of the cycle.
