I'm glad you've decided to TTC again. It's not an easy decision after miscarriage but for me it was the best decision I ever made.
Same as Lyn here, I charted for a month and got Pg on month 2.
After 2 pervious miscarriages (both missed) I decided to get to know my cycles better and I charted my temps and bought some ovulation testers. They don't work for everyone but I found them really good to use.
I did my temps every morning and used an Ovulation stick from around day 9 of my cycle until I got a positive which meant I was about to ovulate (I found it best not to tell OH when the line appeared though in case it puts pressure on at the important time

).
Because my cycle varies between 28/33 days it helped pinpoint ovulation as depending on my cycle it wouldn't always be day 14.
Think my chart is still around somewhere if you want a nosey (Charm33)
But basically like the others have said, try every other day or every day if OH swimmers are up to it

from around 5 days before Day 14.
And see what happens. Or alternatively just try every other day thoughout the whole month, it's hit and miss but as the Spermies stay alive for a few days inside you there should be some around to catch the egg if you ovulate without BDing.
Good Luck, but try not to get too obsessed with it all. It can be very adictive.
