Pressure

I’m 34 weeks and 3 days and this morning I started have weird pressure/ pain that’s starts about by my left hip then goes over and down. It’s mainly when I’m walk but it’s starting to happen when I’m laying down. The baby keeps kind of wiggling around here and there and again I’m feeling that main on the left side. It’s gotten worse and I’m not sure what to do.... it’s my first baby. I don’t wanna go to the hospital just for them to send me home telling me it’s Braxton Hicks contractions. Any idea what’s going on and how to fix it or should I go to the hospital?
