Pressure in lower pelvic/abdominal area

Zay

I'm 38+3 and been experiencing pressure/tightening in the middle of my lower stomach / pelvic area. My stomach goes hard when this happens. Not sure if braxton hicks or early stages of labour. I can tolerate the pain but it's like a mild period cramp sort of pain, still very uncomfortable. Also happens when I lay down on my side. Not close together .. yet. Lasts for about 30-60 seconds.
