I can tell you that the only way to find out if you are pregnant is to take a home pregnancy test or to make an appointment with your doctor and get a check up if you feel that your uterus is moving higher than normal. This is not an early stage of pregnancy by any means. I am close to 26 weeks pregnant and my uterus is just now midway above my belly button. The moving of your uterus takes many weeks to move...Most woman upto 30 weeks pregnant can only feel there baby move under their gut or very low on their abdomen. The missed period is your first sign that you could be pregnant...Or even tiredness...Morning sickness sometimes does not even affect some woman so you can't really go by that eiher...My advice is again to either buy another test in a week or so and make sure you take it as soon as you wake up, oir consult your doctor because again having your uterus move up is not a normal thing if you are not pregnant..And again even if you were this wouldn not be happening yet. Good luck!
