Heavy lifting 33 weeks pregnant

I am 33 weeks pregnant, I am currently moving home, and I am the top floor in my flat so it’s is like 3 flights of stairs..

We were moving stuff up, I took up some bags with my baby’s clothes ( the stuff wasn’t too heavy ) but I took up a couple of bags at a time, I’m just worried now.. has anyone else ever had to do heavy lifting, or knows what the risks are behind it? Thank you
