Don't know what to do...... Please help!

I'm having horrible pain in my belly button. I can't even touch close to it. It hurts when I do anything but lay on my right side. My daughter is kicking a lot which also hurts when she kicks near my belly button. My dr doesn't have an answering service on the weekend and I called labor and delivery but they said they can't answer medical questions over the phone. This is my first pregnancy (I'm 27 weeks) I don't want to go in if this is something normal but I just worried it's something more because of how bad it hurts..... Should I just go in to be safe or wait until tomorrow when my doctors office is open?
