Im 17 weeks and and this is my first pregnancy. I've been really trying to pay attention to different sensations. I just had this feeling that was similar to gas, but I noticed that it felt more like something was pushing my stomach from the inside. It was definitely not a swift bubble feeling. It was a feeling like a push from the inside that sort of held there for a couple seconds. It happened a few times within like 3 or 4 minutes. Does this sound like baby movements?
