Advice, maybe?😬

I'm almost 36 weeks, I'll be 36 tomorrow. Today, I've noticed that I've dropped a bit, which is no big deal. However, I've also had some uncomfortable cramping in my lower back and abdomen. No discharge. I think I'm chalking them up to Braxton hicks for the moment, but do those get somewhat uncomfortable or slightly painful? I talked to my doctor's office earlier when they called with an appointment reminder for the 14th of this month about it, and they didn't seem the least bit concerned. Does that mean I shouldn't be concerned at the moment? If it gets worse I can probably call, but in the mean time, does anyone have any peace of mind to offer?😂
