I decided back after my last cycles post that it really didn't make sense for us to be ttc just then; we're building a new house, and being pregnant while doing that didn't make a whole lot of sense (which turned out to be a good thing because had it happened relatively quickly, the house has NOT, and would have made things, um, interesting).
In the meantime, I've been tracking my cycles. It's interesting to me, while they generally tend to be around the normal 27-28 days, I O a few days late and then have a short LP. Here's the list so far:
Cycle # CD of O LP length
1 37 6
2 22 6
3 23 7
4 21 9
5 21 9
6 15 9
7 20 10
8 17 10
9 18 10?
(The last is a ? because it hasn't happened yet. And maybe it won't...)
It's nice that my LP has been getting marginally longer each month, usually about 6-12 hours per month. And yes, I have been somewhat obsessive about all this tracking!
