So of course, I've been feeling my little karate baby for a few weeks now. I have no problem telling the difference between gas and kicks. But I'll get a bubble like thumping on my left side, like right at the bottom of my ribs, and almost the same spot every time. Not sure if baby is that high up or its just a muscle twitching. It will come and go. Only started when I laid down a little while earlier. I personally feel like my uterus and baby are very low for 17w 6 days. So I feel like it wouldn't be kicking. But it's for sure not gas.
