With my daughter I dont remember when I started getting them but I did have to have my labor stopped at 28W cause I went into labor with her..
This is my second pregnancy and I'm 28W lol and I have been having braxton hicks for about a month and they just get stronger and more painful and uhh they are so uncomfortable. I have yet to find anything that helps ease them :/
Sorry not very helpful
I've had it from 20 weeks. Get as much rest as you can and stay well hydrated
