Yes. You shouldn't be moving any heavy things.
Yes, you shouldn't lift heavy things unless your body is accustomed and its something you were already doing pre-pregnancy.
Okay thanks I'm already having Braxton hicks
Me too! Im 28 weeks and with both of my pregnancies I started getting them around 16 weeks. I get braxton hicks if I bend over to tie my shoe or sit in an uncomfortable position, i guess my body is just sensitive. Haha
