So I was laying on my back for a while and noticed this tightening sensation every maybe 10 or 15 minutes I thought I was about to get a belly ache or something...So I finally put my fingers on the spot when I felt it again and what do ya know! It's a firm little ball which is the baby !! Lol anyone else experiencing this at 15 weeks ?? It's so interesting I just want to keep touching them when they press themselves up under my belly button like that lol babies are such a blessing !!! 😊❤️😊
