I'm not sure if this is a pregnancy thing or not....
I am 35 weeks gone, and have managed to train myself to sleep on my left side quite well. However, the last few days I've woken up with pressure behind my left eye - it feels as though my eye has sunk into my skull, or maybe that everything around it is slightly swollen.
It doesn't hurt exactly, but makes me feel really nauseous and squeamish.
Anyone got any ideas about what may be causing it?
