- I have a question:
Do Ovulation and Menstruation happen at the same time?(0 votes)- no
ovulation occurs at around day 14
whereas menstruation occurs on day 0
menstruation is the shedding of the endometrium layer, the layer that the embryo is meant to implant itself and grow
if menstruation were to occur during ovulation (the release of the egg) then that egg would have no where to implant(1 vote)
