Need opinions! So I'm 18w5d and so far I haven't been sure about feeling my baby move. I've had a few instances where I maybe felt him but didn't know if I truly did. Tonight maybe a half hour after eating and laying on my back propped on the couch I think I may have felt it. It was the first time I've actually felt like omg that was him but I'm still not sure since I'm a first time mom. Would if feel like actually kicks not pokes or was a I just feeling things from eating? They felt pretty strong but I've never felt anything before, would feeling movement like this just suddenly happen?
