Just started ttc and I thought dtd on ovulation day was the best possible time but I've been reading a bit and some say its better to do it just before ovulation. Asking this as we didn't have the opportunity on the other days but felt quite hopeful that we managed on the actual day. By ovulation day I mean the day the egg is actually releasing. Know when this is as I get a lot of pain on my left hand side when it's happening. What do you think? :-) Oh, btw, i'm in my forties, so don't have time on my side.
You're much much mor likely to get pregnant in your fertile period which will span just over a week for most ladies. The 5 days leading up to, 2 days or ovulation and 1/2 days after ovulation combine to make up your fertile window so that's when you need to be doing the deed!
Sperm can live in the vagina for a few days hence why it is possible to do the deed 5 days before ovulating and conceive!
Of course there's no guarantee whenever you do the deed but if you are doing so in your fertile period you will have a much higher chance of conceiving!
