Just about 34 weeks now and for the last 2 weeks I get an ache in my back only on the left side it's not low either feels up higher and usually kicks in when I'm sitting for a while then makes it hurt to breathe and I have to stand up. Now today while I'm still dealing with that I'm having random period like cramping only down on the right where baby is. It gets worse after I eat and feel full and I can sort of ease them if I shift and lay on my left side. This is my first and my next appointment is on Wednesday so I'm trying to see if any of this seems normal at this point or if I should worry at all?
