I just wondered if you all mix it up with timing of sex? I realise that timing is everything with regards to conception and something I have been reading in an SMEP book got me thinking about the timing of when my DH and I have sex - which is always at night. Many books tell you that sperm can last for five days and the egg for 24-36 hours. While this is technically true on the very long end (and something to follow if you trying to AVOID getting pregnant), most sperm will only last about two hours if you do not have fertile-quality cervical mucus for it to swim in. .... sperm in runnier mucus will live about two days, and will be up there and ready for the 12-hour life of the egg. I realised last night that when we conceived our son we had sex only once that month - at about 10-11am on a Sunday morning after a +Opk (because we could back then! ) but we literally haven't had sex anytime other than bedtime since my son arrived! I hate sex first thing in the morning - but with a toddler that doesn't sleep well & gets up at silly o'clock it would be difficult anyway! I work all weekend, so spontaneous nookie at brunch/lunchtime on a Sat/Sun is off the cards too.... Obviously any afternoons & evenings are very tricky whilst dealing with a toddler although my husband isn't available 99% of time then anyway! I wonder if this might be why lots of people fall pregnant on holiday too - as sex is more frequent & possibly timed differently? In theory we could be constantly missing the egg if timings mean sperm & egg never meet because my DH sperm & my egg need to meet as they did when we conceived our son?!
