While I was searching I found this link someone posted... Its a calculator which adjusts your bbt to a different temp if you tested earlier or later than usual. I put my temp where I took it 4 hrs late and it put it to .2 degrees higher.... Very curious!

Just be careful with the adjusters because I know for me, my temp doesn't really make ASA much of a difference as they say and sometimes its much more. My RE actually just told me that taking it and using ur actual wake up temp is more accurate than the calculators. My first cycles doing BBT I too used that same site but u started noticing that those sites just didn't work for me. Its completely ok to use it in the TWW since a single temp doesn't matter much, many women do, just be careful before O because it can make it look like u have higher pre-O temps which could make it harder to pinpoint ur O rise. If possible, its best to try and wake at the same time for ur temp, even if u fall RIGHT back to sleep. I just keep my phone or a piece of paper next to my bedside and that way if I want to sleep more, I can
lol. Just wanted u to be aware that the temp adjustments def differ for everyone but who knows, it may work much better for u then it did me!
Anyway, can't wait to see ur temp today! FX!
