I am a first timer, so I don't know what to expect.
I am 22 weeks pg, and for the last 2 or three weeks I have been feeling little "bubbly" feelings in the area around my pelvis/belly button. A bit like my blood going bubbly for a few seconds? I feel it mostly when I am sitting or lying still. Nothing really tangiable like a kick or anything yet. DH reckons it's LO practicing his bowling action!
