Placenta Previa
A fetus can die inside you but not come out so then it is still a miscarriage. You have to see the doctor if you suspect a miscarriage.
It mean that she has had a miscarriage before the full term.
You need to seek medical attention as soon as possible. Even though you have a miscarriage it doesn't mean your body removed everything from the pregnancy. If you still have part of the placenta or baby inside your uterus it could cause severe infections.
It might separate from the wall of the uterus causing a miscarriage.
An ultrasound scan will show if you have had a miscarriage. Sometimes you may bleed from near the placenta (afterbirth) but you don't miscarry and it will show this too. Sometimes you bleed and lose the baby but not all the placenta comes away which can be dangerous, causing bleeding and/or infection. the ultrasound scan can show all these things.
Will pregnancy test still read positive after miscarriage?
You miscarriage almost three ago and still lactating why?
probably not, what it means is that your hormone levels are still high enough to register on a home pregnancy test, most like due to how far into your pregnancy you were at miscarriage... however! you really need to see your doctor immediately.. it is also possible that your placenta abrupted & you are still pregnant..
