Without any other temps, I think you Oed cd 35. It is a low temp and then you steadily go up. It's also the second day of your positive opk. I wouldn't think you Oed earlier wi only high readings. Plus, if your opk went negative on CD 36 mine always goes negative the day after O. I don't check cm, but it can be influenced by other hormones so you may have been gearing up to O and then didn't which is why you have so many days of ewcm. As far as the cervix, I also don't check my cervix so I'm not help there.
The only other arguable time I see is CD 30 but your cervix was closed and I'm pretty sure it is supposed to be open.
So being 2dpo, bding likely won't benefit at this point. But if you are still having unsure signs it doesn't hurt to bd and if your temp is still up tomorrow then you can count o as cd 35. If not, then you covered your bases.
****(now that it's the next day CD34-38 are real temps)****Oh, no. You're reading the chart wrong, hun. If you look, I said that the only REAL temps are from CD 34-37. ALL of the others are ghost temps I just made up so FF would put up crosshairs, bc I know that I O'd, I just didn't have the pre O temps to "prove" it to FF. So CD30's dip isn't anything, it's just a fake temp. Even CD38's temp is fake so it will change tomorrow after I actually wake up and really take it. My question/questionable O days are CD35 or CD36. I have a VERY noticeable shift in temps, that's why I know I was still pre O when I started BBTing again. My pre O temps are always in the 96's, and when I get close to Oing the always dip down into the very low 96's, then immediately following my O, they jump up to the mid/high 97's/mid 98's sometimes higher. If you look at my previous charts you will see what I'm talking about. Which normally directly after I O, the very next day it shoot's up way higher then it was, it's not a gradual shift. BUT last month it put my O date as the last temp previous to it shooting up a lot higher, charts before that (which have been one day low 96's, next day 97's) it always put my O day as the last LOWEST temp that I had, probably bc it's not a gradual change, it just shoot's up overnight. Last month it didn't do that, I had one or two temps after my lowest temp that were still in that 96 range, and it put my O date as the last temp previous to the shoot up to the 97's, instead of the lowest temp like it had been previously. That's where I'm confused. If I go by the lowest temp then of course O day was CD35, but since CD36 wasn't that much higher and was still in the pre O range, is that really my O day? Esp, since I still had other symptoms of being fertile? Is this making sense? LOL. I know it will shoot up in the morning, but if I released an egg late yesterday, then maybe, just maybe we still could have a window of opportunity to get some more swimmers up there before the gate closes for vacation? lol Do you understand what I am saying at all? Look at last month's chart, which I didn't have an immediate shoot up high, like I am this month, and then look at the previous two to that, where it goes way low, then shoots up way high. Those two are obvious to me that O'd the day of that last lowest temp. It's the ones where I have one straggler temp that is still pre O range that stumps me. I know you have been on here for a while, is there a "FF chart expert in the house that I can have take looksie for me, that you could possibly refer me to?"
P.S. Sorry post is so long. This cycle has been nuts confusing and I'm trying to make sense of it all now that I am starting to chart everything again. Also what do you make of the putting in a "BD" session on CD35 bc we BD'd that previous evening/early am and I put in a softcup, so technically the swimmers were still in there on CD35, we just did not actually BD...get what I mean? That count's too, right!?!?!
