im a bit confussed,iv been reading up on the net about ovulation but its not very clear.. is it best to have intercorse on the day you ovulate? or 2 days before you ovulate? so when you ovulate is that it untill the next month,i mean if ovulation day is today,and you did not have sex in the last few days,then have you missed it? and whats the most obvious sign of ovulation??/ thanks xx
