I'm only 18 weeks but I have quite a large (and growing) fibroid too (so I'm guessing there's extra weight in there). I'm finding at the moment I'm waking up in the night with a very achey bump.
It happens if I lie on my left side or the right - I'm comfiest on my back (although I know you're not meant to lie on your back!).
I do sleep with cushions propping up the bump and between my legs and when I turn on to my back from being on my side, my whole stomach feels very hard and rigid.
Anyone else get the same? Anyone know why my stomach goes so hard?
