Carrying groceries?!

Me

I am almost 6 weeks pregnant with my first baby so I am a little worried about everything! Lol I live on a third floor apartment (3 flights of stairs). Is it safe for me to carry up groceries as long as I take it slow & don’t carry too many at once? I am used to carrying things up these stairs since we’ve lived here for over 2 years. I just don’t want to do anything that would potentially hurt the baby! Thanks!
