17w and having painful Braxton Hicks

Ali

I'm 17weeks and experiencing painful Braxton Hicks tonight. This is my 4th pregnancy and I don't remember them being this painful. I've only had 3 in the last hour and I did do a lot today. Yard work and deep cleaning a two-story home. Could it just be that I exhausted myself? I did go into preterm labor with my last baby at 36w, I'm scared I'll go into preterm labor with this one.
