I think you're fine. You had a good day to not lift. I cycled overseas and my then DH was back in the States (due to work) when it was transfer time and time for me to fly home. I lifted my heavy carry on, etc. I wanted to stick with the 10 lb limit but it just wasn't feesible traveling 20+ hrs by myself.
Then three days after transfer, day after getting home, I fell down the wood stairs directly on my lower back! I was terrified I did something to the embies we transfered. Nope, two days later at 5dp5dt, I got a BFP (twins)!
Cuddle your little one, and GL!!
