BBT Elevating

Hey ladies I’m have been ttc for years now. I have been noticing my bbt is always up then goes down slightly I am 6 dpo and my bbt has been 98.8 all day the highest since ovation day. Could this be a good sign ! I know it’s still early but my temp is always 96 or 95. This is my first time charting my bbt . I don’t feel sick just warm but cold to touch . Also the other morning I didn’t wake up til about 3pm ! I never sleep in ! Thanks in advance fingers crossed!!!!
