Does anyone else feel like its hard to distinguish between their BH contractions and their baby causing the tightening this late in your pregnancy?!

Honestly, I do not remember having BH contractions/what they felt like with my first two boys because it was 9 and 7 years ago. I was wondering if there is any sure signs of BH contractions to help differentiate between them and baby. He is still and has always been VERY active and strong, I have an anterior placenta (idk if that makes a difference or not) and I am currently 37 weeks exactly today.. I have not yet been checked for dilation or effacment at all (hoping my OB will check at my appt on Wednesday).

Any advice/input/experiences are very much appreciated! Thanks ladies!
