Hello!!
temp drops tend to happen on day of red bleeding for me, so I have a couple of days spotting with high temps, then a drop on what I count as CD1.
If you can last to 18DPO with 18 high temps, you won't need to test, as you are officically pg according to TCOYF!!! Therefore, I would test a few days earlier myself - sorry Ready!! but having said that, in a way it is better to find out later on in pg, as if you find out before you are even 4 weeks, the first 12 weeks lasts forever!!! With DD, I didn't test until 21DPO (don't ask me why I didn't notice that I'd had high temps for that long, but I'd had spotting for 2 weeks, so just thought I was having a weird period!)
Anyway, fingers still crossed Mum and Honey - no temp buddies thread over there, but is a TTC graduates thread that we are all on - we'll save some space for you all!!! Won't be long til you are all with us.
Lottie, sorry to hear you are not doing well - DP/DH's don't half choose their moments do they? I hope you are having a better evening?
Take care all - got to check on supper.
