I am 36w 3d and been having contractions since about 1:30 am this morning. They are not real regular and not all are painful but I do feel like it's period time. Been crampy a lot. I am on bed rest for chronic hypertension. I have heard that walking can make the contractions regulate if it is labor. I am worried if I get up and walk my bp will go up. Would you guys try it to see if they regulate?
