Painkillers in pregnancy

Abbie • Pregnant with baby #1 so excited!!!
Hiya ladies!
​I've been getting really bad back pain, at the moment the only thing that has been helping me is taking 2 paracetamol every few hours. I've been avoiding taking them but today I couldn't even sit down properly so I had to take them.
​What are your views in painkillers during early pregnancy? I'm scared to keep taking them even if it is the recommended dose.
