Pressure/ pain in lower back and lower abdomen

Hey ladies! I’m 32+1 today and for the past few days I have had some pretty uncomfortable pain/pressure in my lower abdomen and back while laying down. It would go away if I changed positions and then slowly come back. Now it doesn’t matter if I’m standing or sitting or what position I’m in. The pain/pressure has been pretty constant. It eases up every now and then but other than that it’s pretty consistent. Is this pretty normal or should I call L&D?
