Could this be an umbilical hernia?

I am 29 weeks and I’ve had ab separation for like half of this pregnancy. Literally the whole area from my belly button upwards has been super soft, and if I accidentally use my abs they stick out like a cone above my belly.

I started feeling a pain and inch or two above my belly button and I feel a tender hard lump there. It doesn’t go away when I push on it. I don’t think its baby because I have anterior placenta and don’t usually feel him there. Pressing on it hurts and has made me feel ill and now my intestines are bubbling nonstop. I’m worried this could be my intestines... what do you think? Should I call my doctor or should I just forget about it until my next appointment?
