I need some advise :)?

yes, you maybe pregnant. Just so you are aware, I am 9 weeks and my urine and blood tests are showing negative results. I had all the symptoms and the gut feeling that I was preggers. Please don't get dicouraged because you see a negative. Also, if it is the first few weeks (first month) then the baby is too small to see. they told me I wasn't pregnant because they couldn't see it and all my test were negative, but I made them do another ultra sound this month and sure enough there was a little baby. Keep hopes up and know that negative tests don't always mean you are not pregnant lol.
