Lifted something heavy! Should I worry?

Ta

Hi guys,

Just found out I was pregnant.

I'm 4w5d, but I helped someone lift an old oven onto a dolley yesterday. My back hurts a bit from it but it's not a crampy feeling.

Should I be worried? Ive had two miscarriages (one before my son, one after).

Any experience with lifting heavy things? Any advice? Please share your stories!

Thanks!
