Hi Jbrd, thanks for the positivity about my timing. I feel good about it, though I know if I was totally committed to ttc I should have had SWI every day for a week before ovulation. But in reality, that is just too hard for a couple of oldies dealing with the usual stuff: aging parents, annoying sons in their early 20's (one unemployed muso who has no concept of how to budget, the other hard-working but still living at home and has lost his driver's license so we are driving him to work and back daily
), a young son who isn't very well at the moment, plus work and general tiredness!
Anyway, it is just as well there are opk's otherwise I might miss the fertile window entirely. Which I think may contribute to the lower rates of pregnancy in over forties - I know it is mainly due to hormonal imbalances and egg quality, but the lower rates may also be due to the fact that we aren't exactly shagging like bunnies as we get older (life has a way of wearing us out).
Anyway, I am happy with the efforts and have had a rise in temperature today, combined with O pain I felt whilst swimming (about 7 hours after DTD) has me concluding I did ovulate yesterday.
Green, my DH seems to have no idea about the fact that I am more interested at a certain time. He doesn't really know when I have AF so there's nothing much to base assumptions on. And I do try to have SWOI occasionally too 
Jbrd, I understand how frustrating it is when your DH is less committed than you are with lifestyle changes. I realised early on when we were ttc our DS, that DH wasn't going to go the extra mile. He would take the sups if I handed them to him and said, "take these", but I couldn't get him to stop drinking his beloved red wine nor stop him having the occasional smoke (which really upset me). In the end I just had to accept that I was doing my best and I could encourage him, but had to draw the line at nagging and feeling frustrated. I sympathise.I doubt that his heart isn't in it, more that he feels that it will be okay no matter what he does. I do think men have a touch of the "I'm invincible" about them.
Jass, I really understand where you are coming from. I think,having early miscarriages, every new day that you get with a pregnancy is to be celebrated. I am so hopeful that this one will be your THB.
Well, it is the night after DD's ball. She did scrub up well - looked very pretty. I now wish I'd put something nice on and did some teacher duty at the ball so I could have seen her with her friends, but it was her night and she didn't really want her parents there.
So, that's another milestone. As I was driving home, I did wonder, how strange would it feel,if I did get pregnant again, and have a THB, and would be driving them to their school ball at the age of a grandparent (I'd be 65
!!!). It's a weird thought, but I think I'll be a young 65 (I hope).
