Symptoms?

I’m 6dpo today, I know it’s too early to have proper symptoms but I’ve been using these:

Sore boobs (I struggle with anything even lightly touching them), bad cramping and ovulation type pains, sore throat, headaches and HORRENDOUS nausea. With PMS I usually get sore boobs and cramping but typically in a few more days and significantly less intense. Could these be very early signs?
