BH or contractions? 36 weeks Thursday

Diana

It’s crazy.. I can’t figure if I’m actually having Contractions or BH since I’ve had two other children but I had them 20 years ago so don’t recall. I will be 36 weeks this Thursday and I’ve been having Braxton Hicks since 25 weeks and now I noticed for the last two days I have them way lower in my pelvic area along with dull achy cramps in my back, not front! I do have an anterior placenta so not sure if that changes it, but cramp like feeling almost in my entire back when having super intense pressure and tightening in front is making me question them. I’ve been drinking plenty of water and me moving about doesn’t stop it.. What are your experiences? I have my 36 week appointment tomorrow. Hoping they will check me!!
