positive home preg tests and neg doctors test

[dmestiza]

there was blood in my urine from vaginal bleeding... i did so many tests over a few days... and most were negative but the 3 tests i did were distinct dark positives... so i will test again at home next week and see if i get any positive results... also, if a preg test is a purple dye test, would it be normal if a positive test line was dark pink/red in colour... kuz thats the result i got (but on the test instructions it says any pink colour is positive)... but my doctor said it was positive and im pregnant... which i still dont know 100% kuz of the negatives i am getting when i test...
