hi having sex on ovulation day is not a good way to get pregnant it needs to be 3 to 4 days before so his sperm is there waiting for your egg. if over the last cycle you have been stressed then this could be just one of a few to why your missing your period. so have you been stressed? if you think your pregnant then do go for a doctors test. good luck
