what is the reason to bleed during 3rd trimester of pregnancy?

Answer 1

depending on what week you are in, could be a number of things.
First you will loose a mucus plug from your cervix, and you might spot at this time. Then when you begin to dialate you will spot a little, the more you dialate, the more you will bleed. Either way, you should tell your obgyn asap. Just to be on the safe side

Answer 2

Infections: Spotting can also be caused by conditions unrelated to pregnancy. A vaginal infection (such as a yeast infection or bacterial vaginosis) or a sexually transmitted infection (such as trichomoniasis, gonorrhea, chlamydia, or herpes) can cause your cervix to become irritated or inflamed. An inflamed cervix is particularly susceptible to spotting after sex or after a Pap smear. You may also spot or bleed after sex or a Pap smear if you have a cervical polyp (a benign growth).

Placental problems or premature labor: In the second or third trimester, bleeding or spotting can be a sign of a serious condition such as placenta previa, placental abruption (in which the placenta separates from the uterus), a late miscarriage (between 13 weeks and midpregnancy), or premature labor (between midpregnancy and 37 weeks).

Normal labor: A mucus discharge that's tinged with blood after 37 weeks is most likely just a sign that the mucus plug has dislodged and the cervix is beginning to soften or dilate in preparation for labor. You should still report any other bleeding or spotting at this point to your practitioner.

Unknown: In some cases, the cause of the spotting will remain a mystery. About 20 weeks into her first pregnancy, teacher Laura Graff discovered she was spotting. Her doctor was concerned, so he advised Graff to take it easy for a while — to skip exercising, stop having sexual intercourse, and avoid lifting heavy objects for three weeks. After a week, the spotting stopped. Her doctor never figured out why it had happened, and Laura's son, Kevin, was born healthy at full-term.

Note: If your blood is Rh-negative, you'll need a shot of Rh immune globulin whenever you have vaginal spotting or bleeding (unless you know for sure that the baby's father's blood is also Rh-negative).

Answer 3

Book 1: "If you start to bleed at any time during the second or third trimester, call your maternity unit and go there as soon as you can. There may be serious problems with your placenta, or you could be going into premature labour, but there are other less serious causes. It's important to be seen right away, just in case"

Book 2: "Light or spotty bleeding in the second or third trimester is generally not a cause for concern. It is often the rsult of trauma to the increasingly sensitive cervix during an internal exam or sexual intercourse,or simply of causes unknown. Occasionally, however, bleeding is a sign that immediate medical attention is needed. Since only your practitioner can determine the cause, he or she should be notified if you experience any bleeding - immediately if the bleeding is heavy or accompanied by pain or discomfort, the same day even if it is only spotty and there are no accompanying symptoms. Ultrasound examination can often determine whether or not a problem exists.

The most common causes of serious bleeding in the second or third trimester are:

Placenta previa or low lying placenta: Bleeding is usually bright red and painless. It most often starts spontaneously, though coughing, straining or sexual intercourse may also trigger it. It can be light of heavu, and it usually stops, only to recur later on in pregnancy.

Abruptio placenta or premature seperation of the placenta: Bleeding may be as light as a light menstrual flow, as heavy and a heavy one or much heavier, depending on the degree of seperation. The discharge may or may not contain clots. The intensity of the accompanying cramping, pain and abdominal tenderness will also depend on the degree of seperation. With a major seperation, signs of shock from blood loss may be evident.

Other possible causes of bleeding: Occasionally, the uterine lining may tear, causing heavy bleeding - as any cut might. There may also be crampy pain involved, due to the accumulation of blood near the cervix. Bed rest will usually allow the tear to heal.

Late miscarriage: When miscarrriage is threatening, the discharge may at first be pink or brown; when bleeding is heavy and accompanied by pain, a miscarriage may be imminent.

Premature labour: Labour is considered premature when it begins after the 20th week but before the 37th. A bloody mucousy discharge accompanied by contractions oculd signal preterm labour"

Answer 4

I bled at the beginning of my last trimester. I was right at 7 months along. I called the doctor immediately (hope you have as well) and he sent me to the ER and it turned out to be because I had had sex. There is extra blood down there when you are pregnant and the whole area (inside and out) is more sensitive. the friction can very easily rupture blood vessels.

That said, if you are bleeding I IMPLORE you to call your doctor right away or get to an ER. It could also be very serious. The placenta could be detaching prematurely which means that you could loose your baby and could hemorrhage and loose your life as well. It is VERY important that you get MEDICAL advice. None of us here are doctors and even if some one who answers this is an actual MD, do you really know that they are and not just say that they are? Unless it is a considerable amount of blood, it is probably nothing major, but it could be. Why risk it?

Oh! Also, sometimes during very late stages of pregnancy, you will loose you mucous plug (so very gross) and it can have some blood in it. You could also be starting to dilate and in doing so be breaking capillaries which will bleed. Or even, if you went to the doctor recently and had an exam, that could cause you to bleed. Hope this helps, but I still advise you to see your doctor.

Answer 5

If it is like a period bleeding, then you need to contact your OB right away. Usually towards the end of the 3rd trimester you loose your mucus plug, which is like a light spotting. All that is, is to get you ready for labor. Once that happens do not take any more baths, stick to showers.

Answer 6

sometimes labor starts with a lil bleeding. I started to bleed with my 2ed child at 37 weeks the day she was born. I went to the hospital I was dialted 4cm and contracting. BLEEDING always requires a doctor vist. THAT is how my labor started.

Answer 7

You need to ask yourself a few questions first

1)how heavy is the bleeding?
2)how many pads are you soaking?
3)what is the color/texture of the bleeding?

Then you need to write down those answers and explain those things to your doctor/gynecologist. It's better to be safe than sorry in that kind of situation.

Answer 8

If someone is bleeding this late in their pregnancy, they need to get to a doctor asap. It is more than likely serious.

Answer 9

Stress

Answer 10
