Any hope?

I experienced an early pregnancy loss two months ago and Drs said to wait a cycle then TTC again after AF. Of course, because of PCOS, AF was a no-show & since I didn't expect it to show & had given up after a 7 week wait with lots of false starts based on CM readings (so unreliable!!), I wasn't opk'ing (just temping out of habit). This morning my bbt rose markedly. I think I O'd yesterday. DH and I hadn't BD'd in 10 days because of work pressure so we did an emergency BD this morning but I think it was too little too late. Can you share any encouraging or hopeful stories/advice on people still catching the egg in situations like mine?
