As long as there was no pain/injury while doing it you should both be fine. Any concerns are worth getting checked out though. Im 38+2 and am constantly moving and carrying heavy things and have all my pregnancies as hubby works away and i have no family within 2hrs of me. It can't be avoided when u have other children i have 2 toddlers 15 and 18kg that i lift mutiple times a day.
I'm pretty sure your baby is fine, especially since you feel ok.
