Reporter reported that she took the first dose on 22Jul2021 and after she took it, her first menstrual cycle after the vaccine, she started having diarrhea and throwing up. She also had the same symptoms with her menstrual cycle after the second dose. Then yesterday she was sick, had diarrhea and was throwing up. Last night when she went to bed, the alarm went off that her daughter was about to start her menstrual cycle since the mother has an alarm set of when her daughter has her menstrual cycle and she just started correlating this. States it seems coincidental. For her last three menstrual cycles since the first dose of the vaccine she get diarrhea and is throwing up. Prior to getting the vaccine her daughter has never had any problems with her menstrual cycle, she is always light one day, then a little heavier then a little heavier then its over. She was asking if anyone has reported anything like that before, if it has been reported as a side effect of the vaccine. She has had 8 periods prior to the vaccine and did not have this issue.

She cannot recall the date of her menstrual cycles when this occurred. Treatment was reported as declines any. Outcome reported as the diarrhea lasts two days and throwing up only lasts about one day during her menstrual cycle.   No follow-up attempts are possible. No further information is expected.
