Sore back at 5 weeks?

Mo

Trying not to freak... but my back is sore - I slept on it wrong and then lifted a clothes basket for laundry day. Since then, my back has been really sore and I can’t seem to get comfortable.

Is this normal?? I had a miscarriage in 2018 and I’m terrified of losing my rainbow 🥺🥺🥺
