Please help! BBT Charting

Emma

I’ve just started TTC this month. I’ve tried the BBT method, however, sometimes I wake up to use the bathroom earlier than the allotted time window. I did this morning. I took my temp and it was over a degree below yesterday’s temp. I’ve gone back to bed and haven’t slept but just to see I’ve taken my temp again and it’s still well below my reading yesterday. I don’t know if you can say that’s a implantation dip. I’m 9 DPO. I’m not sure this method will work for me lol it’s so confusing! I’ve used the latter temp because the first reading was 35.15 degrees! All my other readings have been in the high 36’s. I’m sure I ovulated, I used ovulation tests and my CM was great. Any help would be appreciated!
