Pregnancy Info HOME

I just dont understand, i took a test on the 7th of feb. and that week i didnt get my period and the test came out positve, and i started bleeding on the 14th (really light) and became a little darker, (bright red), and docotor told me to go home from work and lay down with my feet up... and i did that, it helped the bleeding stop, it stopped the 16th, but by that time it was very light, not even staining, and i had gone to the docotor on the 15th they took a blood test and it came back negative, told me i might have never been pregnant, i have the symptoms, my nipples are sensitive, and they are expanding, and dark, and i cant tolorate some foods, candies, etc., and hungry all the time, dont get full, gained some weight in my stomach, not much, but seems a tad rounder, over all feel pregnant, can i be too early to dected my hormone levels in my blood, can they be too low?? HELP!!
