Sciatica pain. Taking Morton during the TWW

Molly

I’m currently 3 dpo and I’ve been having sciatica pain since my period ended. The only thing that helps is Motrin and taking a hot bath. I was just reading up on Motrin in early pregnancy and now I’m freaking out due to the increased risk of miscarriage. I’ve probably taken a totally of 800mg of three days. Should I be worried. What are some other things I can do to help this pain?
