What's this spike in my chart? 6DPO!

I've never experienced a spike this high after Ovulation, and I haven't been pregnant since starting to chart! Last night I went to bed with cramping on the left side of my pelvis and lower back pain, woke up with a 98.21! Could it be an increase from implantation?! Give me your thoughts! I'll test on Thanksgiving day! 10 dpo! And every day after until AF arrives. 😊

I also woke up with watery-ew cm! Hopeful for the changes!!
