@Workingmama1 that's so true. The charity thing sounds good. It's surprising the little things that make a difference when you're stuck in hospital for any reason - when my son was in PICU after his operation they gave him a lovely blanket from a charity called the Linus Project, which made it all seem less 'hospitally'.
@PurplePansy05 - wow, well done on the C25K! Sorry about the UTI, they are awful.
@Starfish762 Glad scan went ok - how interesting they could see you were ovulating!
I think CB advanced digital need to be fmu for testing for oestrogen, but once you've got the flashing smiley you test later in the day. But I don't know how well it works if you've drunk loads.
I guess if you know you're ovulating now, then if you did get pregnant you could date it from that.
I've been doing more reading and research, and apparently there are several different patterns of lh surge you can have - the 'standard' one where you have one peak that rises quickly and then goes down, a 'plateau' one where lh rises and stays risen for a few days then goes down, and a 'multiple peak' one, which I think I had this month, where you get a peak then a drop then another peak, possibly several times, before you ovulate. This may be because you failed to ovulate after the first peak, or not. Also apparently some women can ovulate 2 or even 3 times in a cycle! They know surprisingly little about all this.
I had peak opks most of yesterday until the evening when it dropped back to high, and todays are high, so I'm thinking my peaks are over, and hoping I ovulated yesterday. My temps were back up this morning (not high, but I do sometimes have a slow rise), cramps are gone, and my weight was down again after a plateau over the past 6 days. So now the dreaded TWW begins.
