ok when a woman is pregnant right she filters the babies blood through her system now does this mean that if the woman was to have someone look at her dna would they find three dna the fathers , the babies and hers?????

actually, yes. In theory, there is a barrier between the baby's blood and the mother's, but actually there is a bit of mixing. If you look in the blood of the mother there will be a very small percentage of cells from the baby. In fact, a few blood cells of the mother begin to reproduce in the mother's body. Years later there will be some baby's blood cells in the mother's body.
However, the percentage is very small so it isn't going to mix up forensics or paternity testing.

I personally don't know about the baby's blood cells, but it sounds like Cindy B is probably correct on that one.
I did read a short article in Scientific American a few years ago though in which they found that some embryonic cells from rat or mice (I'm not sure) embryos for some reason entered the mother rat or mouse and ended up in certain regions of her brain, so that you'd find the baby's DNA in the mother's brain. At the time they didn't know whether that happens in humans as well or not, and odds are they still don't know, but you can try googling for it. I'd say there's a fair chance that it happens in humans as well, but obviously I could be wrong.
The only way you're going to find the father's DNA in the mother is as a part of the baby's DNA.

No, the only place the father's dna would be found is in the sperm. Once the egg is fertilized, it merges with your egg dna to form the child's so only yours and the baby's will be in your system. However, I have recently learned that because you do filter the baby's blood that the dna of children you have can remain (in trace amounts) in your blood stream for around 26 years! Hope this helps!

The baby's DNA stays in the womb, although some hormons will indeed enter the mother's system. The placenta allows an exchange of food, waste, and chemicals, but the baby's blood stays separate.
The father's DNA is only present as part of the baby's.

The baby's DNA doesn't flow through the mom. It's in the baby and the placenta. The mother's body is creating more of it's own blood to give to the baby. That's one of the factors in gaining weight, feeling dizzy, varicose veins, etc. Their is a significant increase in blood volume for the mother.

The babies blood system and mothers are completely separate. Your babies plecenta is what filters your babies blood. Your blood and your babies blood never mix!!! I am sorry, that would make it a lot easier then having to have amniocentisis for parental determination.

The baby's blood and mother's blood do not cross, so the baby's DNA would not be in the mother.

No. If they look at the baby's DNA they will find all three

No, all three of you would need to get a DNA test.
The father the baby and you, the mother.

The mother does filter the babies blood. In fact if you are rh negative and the baby is positive then baby blood in you can make you sick, and mom blood in her can mean death or other severe problems.
