Ok, well, first off, you were sick, so that probably delayed your ovulation(and gave you some false high temps...I've been watching your chart...yes I'm a chart stalker

) Looks to me like you O'd on CD 20, and having ovarian twinges on one or both sides for several days before hand is pretty normal(I get them as much as 3 days before and one day after, some cycles) and if you do ovulate 2 eggs(2 from one or one from each) it is within 24 hours, because after that your body is producing progesterone which tells the ovaries to stop producing eggs(except in rare genetical deformities, which is called super fetation and to my knowledge has never been proven)
Anyway, as for the dtd, it's not showing on your chart, for me, you have to go to your *home page setup* and mark the box next to *Publish Intercourse Data* but up to 5 days can happen, but 3 days is a better time frame, for TTC. However, Malachi is proof that 6 days before hand works too

I also have a friend with a 7 day beforehand, so don't count yourself out yet
As for me, I really thought last cycle, that we would be expecting, but alas AF found me, and early, so now I'm on cd 14, and perhaps O'ing *on time* for the first time in a lot of years
