Movements🦶🏾🦵🏾👶🏽🤰🏾

Hi ladies! I’m 21 weeks and 1 day and I still haven’t felt baby move yet. Or at least I think I haven’t... should I be concerned? I have my anatomy scan on Wednesday but I’m just nervous. I do weight about 263 pounds... does that have anything to do with it? First time mom and just wanting to make sure my little peach is okay(that’s what we call our baby :) ) thank you all in advance 😊❤️
