Hello, i have missed 2 menstrual cycles and its been 54 days.my pregnancy test are negative. also, i had fever in past 20 days. please help.

Please see your doct: Doctor you need evaluation of the missed periods and fever the 2 may or may not be related.

Could be: Many things can cause skipped or irregular periods. If you have pain, it could be due to a cyst. Sometimes there can be irregular hormone production, or failure to ovulate that can cause late or skipped periods; also things like stress can cause irreg menses, or thyroid problems. Some lab testing and sonogram are needed to find out exactly whats going on.
