Early braxton hicks?

At 17wks? Have had some big stressful events as of late causing alot of anxiety, anger and stress. I feel that could be why I am experiencing braxton hicks so early? This is my second pregnancy, so yes I do know what they feel like. Im doing everything in my power to relax and look the other way with this family drama shit being thrown at me. Its so hard, especially when u hv a toddler to protect from it. Can really early braxtons be normal? Or is it more stress related?
