Physicians approximate that 25 to 40 percent of women will experience some vaginal bleeding during the first trimester of their pregnancy, and most of the time the pregnancy will progress absolutely normally. Let’s check common causes of bleeding at 4 weeks (+ 1-6 days).
According to the American Pregnancy Association, there are a number of possible causes of harmless identifying or bleeding in the first half of pregnancy, consisting of:
- Implantation bleeding, which occurs about 4 weeks into your pregnancy as the fertilized egg connects to your uterine wall.
- Hormone changes
- Sexual intercourse
- Internal test done by your obstetrician or midwife
In some cases bleeding at four weeks pregnant can be a sign of a more serious condition, however, such as:
- Subchorionic hemorrhage, which is bleeding around the placenta. Although it is possible to continue with a normal pregnancy after this type of bleeding occurs, timely diagnosis and treatment is important. “Most subchorionic hemorrhages deal with, but it does put the woman at an increased risk for other complications such as preterm labor,” Dr. Stephenson-Famy states.
- Chemical pregnancy, which occurs when an egg is fertilized however never ever fully implants in the uterus.
- Miscarriage (either threatened or impending), which is the spontaneous loss of a pregnancy in the first 20 weeks. Frequently, the bleeding or identifying that occurs during a miscarriage will be accompanied by other symptoms, such as cramping or abdominal pain.
- Ectopic pregnancy, which happens when a fertilized egg implants somewhere other than the uterus, most often in a fallopian tube. Sometimes called a tubal pregnancy, an ectopic pregnancy can not advance generally and might be deadly to the mother if left undiagnosed.
- Molar pregnancy, a nonviable pregnancy identified by an abnormal growth on the placenta, and, usually, an irregular fetus.
Any vaginal bleeding during pregnancy can be a symptom of a bigger issue, so it’s crucial that you call your doctor today. Be prepared to give information about the amount of blood you’ve lost and a description of how you’re feeling overall, recommends Laura Riley, M.D., author of Pregnancy: The Ultimate Week-by-Week Pregnancy Guide. Dr. Riley says you ought to insist on being seen if you have any vaginal bleeding that makes you feel faint or soaks through a sanitary napkin. You must also be seen if the bleeding is persistent or accompanied by pain or a fever.
Do I Need To Tell My Doctor Or Midwife About Any Blood Loss?
Yes. All bleeding during pregnancy ought to be reported to your doctor or midwife. Any passage of blood from the vagina before 24 weeks of pregnancy is called a threatened miscarriage or threatened abortion. After 24 weeks it’s described as an ante-partum haemorrhage.
You particularly have to see a doctor or midwife within 72 hours of any bleeding if you have a rhesus unfavorable blood group (e.g. O-, A-). The reason for this is to examine whether there has actually been a possible blending of your baby’s blood with yours. If the blood has actually been blended, it might cause your body to produce antibodies against positive blood.
A positive blood group is more dominant than an unfavorable blood group. It’s most likely your baby will inherit a positive blood group, although you will not understand this prior to the birth. The blood blending does not have any bearing on your first pregnancy. But for subsequent pregnancies, if you have another baby with favorable blood, your antibodies would attack what it believes is foreign matter.
