Probably overthinking this. I’m moving house on Wednesday to a first floor flat. I have a van and friends roped in at night to do the real heavy lifting like the actual furniture. But I have the day off work so I was hoping to get all the rest of the boxes and bags moved myself during the day. The boxes aren’t massively heavy, but there are a lot of them and I’ll be running up and down the stairs from the car. I’m not a particularly fit person. Is this safe to do? I’ll be 14 weeks pregnant when I move.
