Hey sweetie, big hugs hun . I know the frasturation of charting every month, timing the 'deed' and then after all the efforts, AF comes. BUT, you can't stop trying hun, you know it's gonna happen one day (hopefully very very soon) so please don't give up hope.
Even though I new DF count was so low, our FS said it would be extremely hard to get pg naturally. BUT, I still did the charts, the temps and timed everything perfectly in hope of a 'miracle'. I didn't give up hope even though I had a lot more obstacles than you!! (Hmm, maybe I was in denial & prayed to prove him wrong??)
Lan, I'm always hoping, wishing & praying very hard for you to get your BFP soon . You deserve it sooooooo much. Sending you very very sticky vibes for next time and loads of babydust your way

PS This might be a very silly question, but when the temp goes down, does it definitely mean no pg??????

B xxxxxxxx
