I'm 16 weeks along and I've been experiencing really horrid pain in my hips during the night, to the point that it's a little uncomfortable to turn over, restless legs aren't helping either!! Also, I'm waking with really blocked sinuses, something that my friend also suffered with at around 16 weeks. I'm off on a long haul flight in just over 2 weeks and concerned that it's going to be more than a little uncomfortable. Has anyone managed to get extra leg room or an upgrade due to pregnancy related problems?
