Hi Neetie - you should find lots of tips on here! Lots of ladies on here seem great at temping/charting (maybe I'm a bit too lazy). I find ovulation kits (OPKs) are addictive and personally, I find the Clearblue smiley face ones (the dual hormone indicator ones) are the easiest to use, although they're not cheap. Have you Googled 'SMEP' yet? Maybe that's one to try. Are you covering the basics with supplements? There's plenty of lists on here to choose from, but as a minimum, of course make sure you take at least 400mg daily of Folic Acid. Or a good prenatal vitamin (e.g. Pregnacare Conception or Seven Seas from anywhere like Boots) will include your folic acid, plus other good stuff.
Annie - hope your recovery continues smoothly. Just in case it helps at all, here's one more 42/43 year old story for your collection. (I'm avoiding my pre-reading/prep for work tomorrow, you're in luck ...)
I conceived DD age 43+3 (first go naturally) having previously had apalling advice from a fertility MOT at an IVF clinic, who said we needed IVF + ICSI. Obviously we didn't. I had a crazy busy job at the time, plus a new diagnosis of hypothyroidism, so it took the best part of a year (not TTC) to find the time (yes I know that sounds ridiculous) to get back to the clinic, at which point they refused to treat me - WTF? So I went home, cried a lot and must've got pregnant about a week later. Anyway, DD should've been my 44th birthday present, but turned up 10 days early. Had a jaundice-y start, but caught up well and since then has always been >95th centile. She is hard work, just because she sleeps less than any kid I know (I'm sure other mum's think I'm lying when we compare sleep times), but as I don't know any different, I just get on with it. And we seem to be doing OK, e.g. nursery want to move her up to the next class early because she's bright, apparently.
I don't think my experience is all that unusual, I know a few people in RL who had babies at 42/43. Plus I think there's been a good few on this thread. I'm sure Fireflies conceived her DS at a similar age - FF, apologies if I'm mistaken - and toddler FF sounds like an energetic, dynamic little boy. Everyone's different of course, but if you and your DH feel its the right thing to carry on TTC, then IMHO, being 42/43 shouldn't of itself be a reason not to try.
My problem is I'd love a full sibling for DD and the prospects at 45 are supposed to be ... 'less good', shall we say. But whilst hormones and everything else seem to be in working order (minus a blip for some bloomin' cysts) we'll carry on TTC for a few months at least. The idea of having to give up seems (shudder) just awful ... If we were lucky enough to conceive, no doubt we'd fork out for extra antenatal tests like Harmony again, but they're decisions for another day. And if we were super-lucky enough to carry to term, I can't see why I'd suddenly be less able to cope than I was a year or two ago.
My current dilemma is just that I need to try to speed things up. I've tentatively enquired with four IVF clinics who claim to specialise in treating older women. Each report live births with own eggs up to 48, albeit only a few. For example, one said that whilst they're picky about who they accept for OE treatment, of the 4 women 'over 45' treated in 2013 (their most recent year with live birth data) there were 2 live births. Hardly any of course, but still, 50% is pretty amazing. We'll see ...
