Weird feeling HELP!!!

Jennifer

I have been having this feeling of movement in me stomach, but I’m not missing any periods and all the pregnancy tests I take come up negative. Why do I feel this way? Sometimes I think I’m going crazy because I swear I see something poke out and move across like I was pregnant. I have been pregnant twice before and it felt a little like this but this is super weird for me. Is it my IUD? Is my body/mind playing tricks on me? Please help!!
