So, you guys, this is really weird. I temped this morning and there was another rise (I'm only on DPO 5 so couldn't get too excited!), and then FertilityFriend (FertilityFrenemy?) changed my O day to CD 20. Last month it was CD 18, and honestly I've never charted before then, though it appears cycle #1 (no temping) I O'd on CD 18 because I had VERY clear implantation cramps and pinches starting CD 6 but then again that's a soft argument at best.
Anyway, I did have a dip + spike pattern both those (CD 18 & 20) days, I suppose--CD 20's was above the coverline though, and I did have a weird blob of EWCM on CD 19, so I recorded that and I guess FF took it into account. Then I realized I had recorded my perma-negative OPK (NEVER gotten a positive one, though I think my version of an almost-equal OPK could have actually been a positive.. just have low LH floating around? Maybe!) most days UNTIL CD 18, so when I recorded negatives on CD 18 & 19 (the days I actually took them), FF jumped back its crosshairs to put me O'ing on day 18. Then I basically changed all of my OPK's to "N/A", which I think is a little more.. accurate, and as this was happening it was jumping back and forth again!
Crazy right? It doesn't ultimately matter, I guess, or does it? In terms of testing and symptom-making-up-in-my-head it does, but I also worry that with my usually 29 day cycle that luteal phase would be mega short. Though I suppose if I actually had O'd on CD 20 my luteal phase would adjust accordingly? My chart is in my signature. I know this has been SERIOUSLY detailed and TMI info, but what the heck FF!
