Pre-eclampsia?

I'm 40 weeks + 4 days now and I woke up with the tops of my feet a little swollen. When I walk I can feel a jiggle. I haven't had any headaches or pain anywhere else. My mum was telling me that it's a normal part of pregnancy at this stage but now I'm feeling a bit worried. I'm in a situation where I can't call anyone and can't bring myself to the hospital. It's midnight so I have to wait until morning time. I haven't really propped my feet up so the swelling stayed the same all day.
