Negative blood test?

April • Lift you head up Princess. Your crown can`t be that heavy. Love yourself before you love someone else.
Have any of you fellow ladies ever gotten a negative blood test then come to find out later on you were indeed pregnant? Is it possible to get a negative blood test if too early? My doctor insisted that blood tests never lie. But I don't really believe everything a doctor has to say. Please  share me your thoughts and stories! xx
