With my first pregnancy the tests went:
Home test - NO
Dr's office 3 days later, urine - NO
Dr's office 7 days later, urine - NO
Dr's office 5 days later, blood - YES
And it had been over a month, since I should have had a period.
.
Pretty much the same for me except it had been two months and the doctor could already tell I was pregnant from my exam. They just needed confirmation. My false negative is 12.
