It may cause vaginal bleeding. This type of bleeding often occurs without pain. Some types of placenta previa resolve on their own by 32 to 35 weeks of pregnancy as the lower part of the uterus stretches and thins out.
Labor and delivery then can happen normally. If placenta previa does not resolve, you may need to have a cesarean birth. Placenta accreta —When the placenta or part of the placenta invades and is inseparable from the uterine wall, it is called placenta accreta. Placenta accreta can cause bleeding during the third trimester and severe blood loss during delivery. Most cases can be found during pregnancy with a routine ultrasound exam.
Sometimes, though, it is not discovered until after the baby is born. If you have placenta accreta, you are at risk of life-threatening blood loss during delivery. Your ob-gyn will plan your delivery carefully and make sure that all needed resources are available.
You may need to have your baby at a hospital that specializes in this complication. Hysterectomy often needs to be done right after delivery to prevent life-threatening blood loss. Late in pregnancy, vaginal bleeding may be a sign of labor. If labor starts before 37 weeks of pregnancy, it is called preterm labor. Other signs of preterm labor include the following:. Change in vaginal discharge it becomes watery, mucus-like, or bloody or increase in amount of vaginal discharge.
Regular or frequent contractions or uterine tightening, often painless four times every 20 minutes or eight times an hour for more than 1 hour. In some cases, medications may be given. When preterm labor is too far along to be stopped or there are reasons that the baby should be born early, it may be necessary to deliver the baby. See Preterm Labor and Birth. Complications: Diseases or conditions that happen as a result of another disease or condition.
An example is pneumonia that occurs as a result of the flu. A complication also can occur as a result of a condition, such as pregnancy. An example of a pregnancy complication is preterm labor.
Ectopic Pregnancy: A pregnancy in a place other than the uterus, usually in one of the fallopian tubes. Egg: The female reproductive cell made in and released from the ovaries. Also called the ovum. Fallopian Tubes: Tubes through which an egg travels from the ovary to the uterus. Pap Test: A test in which cells are taken from the cervix or vagina to look for signs of cancer.
Placenta: An organ that provides nutrients to and takes waste away from the fetus. Placenta Accreta: A condition in which part or all of the placenta attaches abnormally to the uterus.
Placental Abruption: A condition in which the placenta has begun to separate from the uterus before the fetus is born. Placenta Previa: A condition in which the placenta covers the opening of the uterus. Sexual Intercourse: The act of the penis of the male entering the vagina of the female.
If you have bleeding or any of the symptoms above, contact your midwife or GP straightaway. An ectopic pregnancy is when a fertilised egg implants outside the womb — for example, in the fallopian tube. It can cause bleeding and is dangerous because the fertilised egg can't develop properly outside the womb. The egg has to be removed, which can be done through an operation or with medicines. Symptoms of an ectopic pregnancy tend to develop in the 6th week of pregnancy but can happen later.
This is when the plug of mucus that has been in the cervix during pregnancy comes away, signalling that the cervix is getting ready for labour to start. It may happen a few days before contractions start or during labour itself. Find out about the signs of labour and what happens in labour.
This is a serious condition in which the placenta starts to come away from the womb wall. Placental abruption usually causes stomach pain, and this may occur even if there is no bleeding. This is when the placenta is attached in the lower part of the womb, near to or covering the cervix.
Bleeding from a low-lying placenta can be very heavy, and put you and your baby at risk. You may be advised to go into hospital for emergency treatment, and a caesarean section will usually be recommended. The Royal College of Obstetricians and Gynaecologists has more information on placenta praevia.
This is a rare condition where the baby's blood vessels run through the membranes covering the cervix. When your waters break, these vessels may be torn and cause vaginal bleeding. Path to improved health Vaginal bleeding can happen at any stage of a pregnancy, from conception to delivery. Non-serious reasons for bleeding early in your pregnancy can include: implantation as the egg settles in your uterus the first days sex infection hormones.
More serious causes of vaginal bleeding during the early part of pregnancy can include: An ectopic pregnancy a pregnancy that starts outside the uterus and will not survive. A miscarriage losing the baby early in a pregnancy. A molar pregnancy a fertilized egg that implants in the uterus that does not live. In later pregnancy, the following medical conditions can cause vaginal bleeding: Placental abruption the placenta detaches from the wall of the uterus during birth.
Placenta previa the placenta is lying too low in the uterus and nearly covers the cervix. Preterm labor labor that starts before completing 37 of 40 weeks of pregnancy. Things to consider If you experience bleeding or spotting at any time during your pregnancy, your doctor will want to collect as much information as possible. That will include: How far along is your pregnancy? Have you had bleeding at any other time during your pregnancy? When did the bleeding start? Is the bleeding heavy or spotting?
Does it start and stop? How much blood is there? What color is the blood bright red or dark brown? Does the blood have an odor? Do you have cramps or pain? Do you feel weak, tired, faint, or dizzy? Have you experienced vomiting, nausea, or diarrhea? Do you have a fever? Were you recently injured such as a fall or car accident?
Have you engaged in any physical activity? Are you under extra stress? When did you last have sex? Did you bleed afterward? Do you have a bleeding disorder? Women with bleeding disorders are at risk of complications during and after pregnancy. This includes iron-deficiency anemia, bleeding during pregnancy, and serious bleeding after delivery postpartum hemorrhage.
Talk to your doctor before getting pregnant if you have a bleeding disorder. Also, bleeding disorders are genetic. What is your blood type? If your blood type is Rh negative, you will need treatment with a medicine called Rho D immune globulin. This prevents complications with future pregnancies.
