Contractions??

I’m 35weeks and 4 today and I been having pain in my lower abdomen only my left side and left side of my lower back only like it wraps around but again only my left side. It kinda comes and goes and it’s like a little bit more then a dull pain. Nothing horrible but I definitely know it’s there. I’m a ftm so honestly I don’t know what to really look out for and my appt isn’t until Wednesday of next week. Not sure if it’s Braxton Hicks or just the regular pains
