Period or pregnancy symptom?

I’m 4 days late and I’ve had some twinges in my last area on both sides, usually I only get them on one side just before my period but this has been happening for the past couple days.

My breasts feel sore on the sides (near my armpits), my nipped feel really sore to touch and are constantly pointy!!

We just got a rescue dog that is so well behaved but recently he keeps putting his head gently against my stomach.

Are these good signs for pregnancy?
