Pain when pushing lightly on lower abdomen

Crystal
Ok, I don't know the medial name or whatever for  this area but it's my lower abdomen , right along the line under my fat. I push on it very lightly and it feels like pain all along that line area. From each side of I frontons my stomach .  Is this normal? I am high risk, this is my 7th pregnacy but the first time I EVER been this far along. I am 12 weeks and 5 days (but whose counting right? Lol)
