@AlviesMam naked with a fan sounds idyllic. I am so hot and tired, I didn't even feel like eating my tea so had half a pack of chocolate fingers instead and am now eyeing up the other half...
If she's been active all day, it's likely she will be quieter tonight, but if you're worried about movement, definitely call the midwife and let them make the decision whether they need to see you!
We actually have an air con unit. I was
when DH bought it, but I am so glad of it tonight!! We've had it running in DS's bedroom, as it's south facing and gets the sun all day so is always the warmest room in the house in the summer, but we've taken it out now to put him to bed, so it's all mine 
Baby had a quiet day yesterday, but I was very active. Much more lazy today hiding inside from the heat, and she has been wriggling away. Think she's turned again, thankfully, as the bump is back on one side and the 'heavy' feeling low in my pelvis has gone.
