Earliest symptoms and DPO

I KNOW it's way too early for any actual symptoms, I'm only 3-4 DPO. But I've been having cramping lightly here and there and I never have ovulation cramping and I've noticed breast tenderness at times too. I'm just curious if anyone has had any early early symptoms and ended up pregnant? I can't seem to find any posts with symptoms during this timeframe. I'm trying to be optimistic but also realistic that I'm probably NOT pregnant since we only BD once in my ovulation window, but according to my OPK and glow, that day was my HIGH chance of pregnancy at 33%. I'm just not sure what way to be thinking 🤔
