to start with it felt like bubbles, but as it got further along it felt like a big pulse or muscle twitch. Now it ranges from twitch feelings to big full on kicks and pushes. I def think you are feeling bubs if you are getting them more reg and they feel like pulses etc. It's strange feeling to start with isn't it? But soon you'll be talking to bubs in response to them and rubbing his legs/feet/arms/butt/head etc. Enjoy these feelings cause u sure as heck miss them once bubs is born!
