What is the likely hood that a blood test would come back negative for pregnancy when a woman is pregnant? All of the signs are there, I have had 5 positive home tests, but the doctor has always seemed off and tried pushing abortion pills on me before the results came back and she has offered prescriptions for forcing a period. According to all of my friends and family who have had children said that all of the signs are there. I would be about 10 weeks along, and multiple people have made comments about suspecting multiples. I am mostly concerned with my doctors malpractice due to my age (18) in this situation. I have had absolutely no signs of miscarriage and more signs of pregnancy as the weeks go on.
