Unusual Heart burn @8DPO

Ashley

So long story short. I NEVER get heart burn. Not even after ovulation. Last time I had heart burn I was in my 3rd trimester with my first child. So this is very out of the ordinary for me. It also didn't happen until today. 8dpo. Anyone ever get heart burn as an early pregnancy symptom? Also, I never have a slow rise like this. It's usually up and down after O. Chart for reference.
