Just wondering

Is it normal that my OB doctor is asking for labor signs this early on? I’ll be 25 weeks this Friday. My only problem is Braxton Hicks which I get a lot but not like one after another like real contractions this is my 4th pregnancy. My two oldest children were born at 37 weeks and my youngest I was induced due to preeclampsia. So far this pregnancy has been great no complications 🤞🏽☺️
