Blood pregnancy test??

Question

Is it possible to get negative on a blood pregnancy test and still be pregnant?? I have a friend/ co-worker... who told me that when she was pregnant with her 2nd child, she took a blood pregnancy test and it was negative and then 2 months after that when she was hospitalized cuz of her abusive husband, they find out she was 4 MONTHS pregnant because they heard a second heart beat... u think it could be tru... 2 b 2 months pregnant and have a negative blood pregnancy test???

Answer 1

this is extreamly rare and they could have misdated the pregnancy you are a month pregnant before they can tell...id wait to see if you have a period...

Answer 2

A blood test taken sooner than 11dpo does have a significant failure rate, but if her blood test was done after her period was late, then it will have been reliable. So no, you can't be 2 months pregnant and have a negative blood test. The baby needs the hCG hormone is large numbers (in the thousands) and by the time she was 2 weeks along her levels should have been in the hundreds. However, if they did a Urine test in the hospital, that could easily have been wrong.

Answer 3

I really dont think that this could be true. The blood test detects all hormone & HCG levels in your body. If you were pregnant those levels would be much different compared to if you were not pregnant.  

Answer 4

One of my friends had a negative urine test and blood test. She started to gain wait and went to the doctor again. They did an ultrasound and she was 5 months pregnant. She never did have a postive urine test and at 5 months she had a positive blood test finally.

This is not the normal case though.
