I'd rather be safe than sorry 😰

I'm 28 weeks, wondering if I'm too far along to lift a mattress? I'm nesting like crazy rn & cringe over the thought of all of the dust underneath my bed (it's lifted off the ground a lot) . More info: my bed is a full size but doesn't seem to be over 25 pounds, I'm not going to lift it completely, just push it towards one side of my room while I clean.

I don't have anyone to help me, by the way. Trust me, if I did I'd ask.
