I'm 8w and fairly used to exercise, although not super-sporty by any means. I'm currently maintaining the twice a week HIIT sessions that I was already doing (like crossfit, but not so extreme), with a really good trainer who's adapting the exercises for me.
One thing I've noticed is that with certain movements I can feel sort of clicking in my abdomen/pelvis area. It's not bones, it's like things are moving around inside. No pain. Has anyone else noticed this? Is it normal as things start to grow and shuffle around?
