6dpo temp spike and nausea. A little too early for symptoms?? Month 7 ttc...second opinions needed to keep me sane!

Mr

Morning girls, I would like some more opinions on my chart please as I had quite a temperature spike this morning and I had woken last night a number of times feeling like I’m going to be sick. I’m only 6dpo but it would be my second pregnancy so I’m wondering if it is possible to experience pregnancy symptoms so early?? Could this be the start of a trisphasic chart or am I just getting my hopes in unnessesarily? Thanks in advance. Month 7 ttc
