This may sound like a daft question but how often are you supposed to

?
Every day? Every second day? Three times a week? Every day on the week of ovulation ( if you are lucky enough to know when that is!!)? DH and I have been trying to every second day throughout the month. Is that enough, even at ovulation time??? I am not sure either of us could manage any more, bloody exhausted as it is!! Any guidance welcomed.
