8-9dpo too soon for symptoms?

I don't remember having symptoms this early before when I was PG with my son. But, yesterday and today I've been really nauseous and have had a very heightened sense of smell (I swear my pee has been smelling SUPER strong 😅 and I could smell the guacamole I had for breakfast on my upper lip an hour after eating it) weird... I know. I've also been feeling constipated which I never am. And then today I woke up with sore boobs. Hope I'm not overreacting like every month haha
