I am pg with #2 and felt this one later than DS (almost 2 weeks later closer to 20-21 weeks). My placenta is anterior this time and I'm also about 8kg heavier pre-pg than I as pre-pg with DS. I found it annoying that many people/books say you are 'supposed to feel baby earlier' but if you google it you will find that many people actually don't. Dark choc used to get DS going so I tried that but this bub likes/responds to completely different foods. Good luck, I know it's hard not to worry, I did but am sure bub is fine.
