Don't look too much into your symptoms, they tell nothing. It is only a result of your reaction to the hCG hormone and it changing your body, nothing more. You can definitely set up an appointment to be seen. They will go over family history, do blood work, a pap, as well as give you lists of foods to avoid as well as medicines to avoid/use and if you're far enough you might get an ultrasound as well. You will need to start seeing a doctor monthly, so you can call around.
so i should go see a doctor about it? because i mean i have every single sympton
More than likely, yes you are pregnant. Testing later in the day will often show a false negative as the urine is too diluted to get an accurate answer. For best results you always want to use first morning urine, or hold your urine for at least 4 hours with little fluid intake.
