Contractions and BH

Lauren

How can you tell the difference between and Braxton Hicks and an actual contraction? I’ve noticed a lot generally when I’m laying down I’ll get cramping in my pelvic area. No matter how I try to switch positions it doesn’t always ease up. Eventually it goes away I don’t time them or anything. I’ll get it during the day as well but not as often it seems. I’m 28 weeks now.
