Okay, I'm charting my temp this month. I really have no previous cycles to compare it to. I temped in January and February, but those cycles were 42 and 32 days, because I'd just had my Mirena removed. So they don't exactly show a pattern. When my cycle regulated at 29 days (was there for 3 months) I stopped bothering with temps. Then last month, I had a bunch of symptoms, and no way to tell when I O'd because I hadn't temped.

It turned out I was pregnant, but I had an early miscarriage. Now I'm hoping to get pg this cycle.
The thing is that in the cycles I temped, my lp was 17 days long. So if that really doesn't change for a woman, then in a 29 day cycle I should be Oing on CD 12. But this cycle, I got dotted crosshairs on CD 13. I had negative OPKs on Day 12, 13, and 14. I shrugged it off and kept temping, but my luteal phase temps have been insane. So basically I need some help guessing at what they mean.
Any opinions would be greatly appreciated. TIA!
