hi nova,

so sorry for your loss. I fell pg after 3 months of trying. then i mc'd at 9 weeks (blighted ovum). That was on my 30th bday, in december. we have been trying since then with no luck so far. Have tried OPK's a couple times, not sure if they worked for me. but its worth giving it a go. As vanaithi said, i think temping is good, although once your temp goes up, it means you have already ovulated, so its too late to try...
anyway, good luck trying, hope your wait is not too long
