I am 34+4 and have a strange feeling this evening. I have bad SPD (have been on crutches for ages) so wear a support belt/girdle thing when walking but this evening it feels as if it is on when it isn't (hasn't been on all day as was just at my desk). I mean that it feels as if there is a tight belt/girdle round my hips and lowest part of my bump. There is a band of tight pain across the bottom of my bump as if a muscle is in spasm - noticeable but not difficult to cope with, just uncomfortable. Is this some sort of practice contraction? I've had a few Braxton Hicks but they are just a tightening of the whole bump and don't hurt. I've also been getting quite a few random period-y pains the last few days but this is just such a distinctive sensation. Keeps tightening and then easing a bit but not going away completely. I keep trying to take my belt off but there's nothing there!
Can anyone shed any light? Should I worry at all? Baby seems to be fine and is shifting around as normal.
