what is the difference between low lying placenta and placenta previa?

If the placenta attaches instead to the lower part of the uterus, it can cover part or all of the cervix. When the placenta covers part or all of the cervix during the last months of pregnancy, the condition is known as placenta previa, or low-lying placenta.

As adjectives the difference between perinatal and prenatal is that perinatal is of or pertaining to the time around birth while prenatal is being or happening before birth.

It will be lower in the vagina around the time of menstruation. If you've conceived, the cervix will remain in a higher position. The second noticeable change is in the feel of the cervix. If you haven't conceived, your cervix will feel firm before your period, like an unripened fruit.

During pregnancy, the cervix stays firm and closed until late in the third trimester. It opens, shortens and gets thinner and softer so your baby can pass through the birth canal during labor and birth. In some women, the cervix opens too early during pregnancy or is shorter than normal.

This is quite common, as your baby is growing very quickly now. Your little one presses down on the nerves that go from your vagina down to your legs. You may feel more pressure and cramping as you walk, as the baby is bouncing around in your belly. Lying down on your side for a while can ease your discomfort.

The main functional units of the placenta are the chorionic villi within which fetal blood is separated by only three or four cell layers (placental membrane) from maternal blood in the surrounding intervillous space.

Normally, the uterus squeezes after delivery to stop bleeding where the placenta was. The placenta is an organ that grows in your uterus during pregnancy and nourishes your baby. With uterine atony, the uterus doesn't contract as well as it should. This can cause heavy bleeding after you give birth.

Some doctors specifically recommend that pregnant women sleep on the left side. Because your liver is on the right side of your abdomen, lying on your left side helps keep the uterus off that large organ.

Pathologic Examination of the Placenta When any abnormality of potential clinical significance is identified, the placenta should be sent for pathologic examination. Cultures or additional special studies should be obtained before the placenta is sent to pathology.

Low blood pressure (known as hypotension) is categorized if your reading is 90/60 mm Hg or lower. Low blood pressure in pregnancy is normal and is caused by the rapid expansion of the circulatory system.

You just have to wait until you can take a pregnancy test. A cervix that is high, soft, and open is a fertile cervix. A cervix that is low, firm and closed is not a fertile sign, and you're probably not ovulating yet—or you have already ovulated.

Risk factors for the development of placenta previa include: unusual position of the baby: breech (buttocks first) or transverse (lying horizontally across the womb) previous surgeries that involve the uterus: cesarean delivery, surgery to remove uterine fibroids, dilation and curettage (D&C)

A premature baby is at a particular risk, and many hospital check preemie babies in their car seats before they are allowed to leave the maternity hospital. Lie flat 0+ infant carriers are much safer for any baby: for newborns, older babies, and especially for preemies or children with health conditions.

There will be some blood clots, and you may notice tissue that is firmer or lumpy-looking, which is placental or afterbirth tissue. You may or may not see tissue that looks like an embryo or fetus. If this is a recurrent (not first) miscarriage, you may want to save the tissue for testing.

Both placenta previa and placental abruption can cause heavy bleeding of bright red blood from the vagina. A vaginal examination is often used to help diagnose placental abruption, but could trigger heavier bleeding in the case of placenta previa.

During pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. Since the fetus doesn't breathe air, his or her blood circulates differently than it does after birth: The placenta is the organ that develops and implants in the mother's womb (uterus) during pregnancy.

The placenta produces this hormone after implantation. With a blighted ovum, hCG can continue to rise because the placenta may grow for a brief time, even when an embryo is not present. For this reason, an ultrasound test is usually needed to diagnose a blighted ovum -- to confirm that the pregnancy sac is empty.
