Braxton Hicks after Chiropractor

With my 1st pregnancy I didn't have to see a Chiropractor until about 26-27 weeks due to my sciatica pain. I stopped going because the adjustment always caused very intense Braxton Hicks but it worked really well for my sciatica pain. Here I am only 15 weeks with #2 and I saw a Chiropractor today because I can barely walk from the nerve pain. I can barely lift my son and I need my mobility back. Well I got my usual headache after the adjustment but about a half hour after I got home I got what felt like a Braxton Hicks contraction and then another and another. I'm now just having average cramps but am concerned about having Braxton Hicks this early. I didn't know it was possible even to have them this early. I really need to see the Chiropractor so I can continue to chase my son around and not be in pain but should I stop due to how my body is reacting or is this normal? Ladies who see a Chiropractor do you experience this?
