Faith, I'm so envious of all the swi. Hope you've hit the jackpot this month; chart's looking good. Why would your gynaecologist be dismissive of the charting?
Freelance can't you just re-enter day 1 to get your ov figures back? In response to your questions, the progesterone surge occurs one or two days after ovulation and that's what makes your temperature rise. The temperature stays up until you get your period, when it drops again. If you conceive, then progesterone continues to be produced by the corpus luteum (the cyst on the ovary which released the egg) and therefore your temperatures stay elevated. Sometimes they even jump up to a higher level ? this would be a tri-phasic chart, where for the first part of your cycle your temperatures were low, then on ovulation they jump to a higher level, then a while (not sure how long) after that they jump to a higher level still. FF says you can have a triphasic pattern without being pg and you can be pg without the third phase, so make of that what you will. (Do I sound as if I know what I'm talking about? I'm only slightly ahead of you on the learning curve, I think.)
With regards faint lines, apparently it's easy to miss the LH surge, so might indeed be better to test several times a day. This month I'm just doing it once a day to see whether anything shows up, then I might try more often in future cycles. (I've never done it before. I was going to last month but I ov'd before I started!)
I peed in a sample pot and dipped today and it was so much easier. I'm just worried about colleagues coming in and catching me doing it. If I used a clean cup, say, it wouldn't look suspicious when I was washing it out afterwards but it might look odd coming out of the cubicle with it.
