Is it possible to have 2 home and 1 blood test positive for pregnancy and 2 days later test negative?

Here's the low-down..We've been trying to procure pregnant for 2 yrs. and finally found out we conceived. To our dismay, I started bleeding 4 days later. My dr. be on vacation forcing me to see a different doctor. This dr. said I be never pregnant. But my obgyn said I was, from the blood audition results. I have never be so mad or so confused contained by my life.We dont know if this is a extent, miscarriage, or early pregnancy bleeding. I also enjoy methylenetetrahydrofolate reductase, angiotensin converting enzyme deletion polymorphism, and a VERY high thyroid peroxidase antibody tieter. (normal is <35, mine is 389)

What is designed by periods within a girls body?

I know that false postives are possible with urine test, but in a blood testing, I'm not sure. It is possible that you were pregnant and later miscarried...

I am really sorry for the frustrating situation; I know how you feel because my husband and I hold been ttc for a long time immediately, with no luck. I enjoy a condition also which makes it sturdy to conceive... but you can't give up. Keep the hope, and keep trying.

A false positive is not possible. Practically impossible. A false negative happen more frequently.

I'm not a doctor, but I know that false negative are more common than false positives.
