When is the earliest dpo to start feeling symptoms?

Question

I'm just a few days past ovulation but I have been feeling very sick and can't eat much without wanting to vomit. Not sure if it's possibly symptoms this early or if this just comes with ovulation. I lost my first baby August 31 so i'm not sure.

2dpo woke up no more aches. My tempature was going up and down. Nipples were sore
3dpo-4dpo really just sore nipples. A little moody towards my boyfriend. Vivid dreams
