Is it possible to have symptoms this early

I don't want to read into this too much but...

4 days into my peak ovulation period my breast were pretty sore well fast foward to 2 days after ovulation and they feel like they are going to explode!!!! I have bad dey mouth esp. @ night. and 2 smells have drove my stomach insane ( my uncle,and eggs😁). And my kept staring at me yesterday until I couldn't take it anymore and when I asked him why he was staring at me he said " well u don't look pregnant" I said it because I'm not!!!! 😒😞🤔 Could this 6 yr old be onto something?!?!

1.My period is 2 weeks out is it too early to show symptoms?

2. Is it too early to test?
