Hi there. I'm 24+3 and just developed my obvious bump.
Up until this week I have been a bit naughty and been sleeping on my back. I have had no problems.
But this week I have started to sleep on my sides as my weight is creeping up.
The thing is I am now waking up through the night with pains in my hip and upper leg on which ever side I sleep on. It's quite a painful ache.
I am using a maternity pillow inbetween my legs but I am finding that because I'm sore, I'm subconsciously going back to sleeping on my back.
Does this sound familiar with anyone or has any one got any suggestions?! 
Thanks
