FTM contractions help

Jenny 💙

How do I know when to time contractions and how do I do so? Will they be similar to Braxton Hicks? I think I’ve had the BH (symptom is a tightening sensation for like 20-30 seconds and then it goes away). I’m just confused and don’t want to be in actual labor without taking it seriously....the anxiety is real lol and I’m stressing about everything. 36+4 today.
