Am i going through a misscarrige?

i think it's probably just your period coming. a lot of those symptoms you're naming wouldn't come on until later in your pregnancy. it's really rare to get so many of them at just 3 or 4 weeks. i think you probably just got your period a little late this month. if you're having a miscarriage, the blood would be much more clotty and there would probably be a lot more cramping. if you're really worried about it, you can make an appointment with your doctor. that way they can check it all out and make sure that you're fine and it isn't anything to worry about. good luck (:
