Baby is SOOO low .!

Just turned 33 weeks today and last night I felt baby soooo low . He was below my stomach in my pelvis area . I thought maybe it was too early for him to be that low .? Thinking that only happens when your ready to give birth.Or is this the right timing .? First time mom and it caught me off guard i haven’t felt him ever down there and today I still feel him in my pelvis ( not the best feeling ) on top of having serious lighten crotch or Braxton Hicks . Not really sure the difference .
