Pulled back

Poppy

I've just bent down to pick something up and just to add to my long list of complaints and moans I've pulled my back out. I can't afford to lay up and rest as I have school run to do in the morning and hubby can't do it as it's his first day in a new job. My mum sent some deep heat down but I've read it's unsafe in pregnancy. Please does anybody have any pregnancy safe remedies? Xx
