Munkii so sorry to hear your news, look after yourself.
Bean I think the idea behind testing twice a day is that sometimes you can miss the surge all together. If you never get any positive results, then test twice a day and you may get a positive - implying your surge doesn't last 24 hours, but only say 12 or 18 which you can miss with testing once a day.
Popcorn what magazine, if you don't mind me asking? Or if you have any books etc to recommend. I've really got into knitting recently, but would love to learn some crochet as well. There are so many books out there on knitting and crochet now, I just don't know how to choose!
Generic fingers crossed for you this month, and also good luck with the self control. I always tell myself not to test till I'm properly late, but never manage it. AF either turns up when expected, or I test the day before. Unfortunately all aspects of my cycle are variable, so even knowing my ov date my lp varies by 2-3 days. The plan is to always wait for 18 dpo, but I never expect to get that far, and something about doing a test makes it possible for a bfp... like buying a lottery ticket.
I read somewhere that the best time to get pg is with sex at 6am. Not sure if there was any science backing it up, or where I (and DH) read it. We are never, ever up at 6am though, so that doesn't happen in our house. DH does prefer morning SWI to night time though, however I like to lay down for a while afterwards (so the swimmers have gravity on their side) and morning is a bad time for that, unless it's the weekend.
