Ive been feeling movements hermano despite this being my first. I started noticing a weird sensation around my uterus area, particularly after doing something active. Others might say I'm imagining it and it's just wind but after years of dealing with gut related issues I'm very aware of where and what my normal bowel sensations feel like!
Last night I swear I felt a tiny kick in bed, I'd just been up for the loo and was feeling the usual stretchy cramping feeling when I got back into bed, and when I was just drifting off to sleep again I felt a tiny 'pop' sensation! Maybe I was dreaming but I prefer the explanation that it was baby kicking 
Plus my sonographer told me my placenta is growing on the back wall of my womb and this apparently means I'll feel lots of movement, especially later on.
I've just been to my first body pump class in 9 weeks, it turns out the instructor is a pre and post natal exercise specialist and she's going to send me some links of adaptations in classes is anyone is interested!
