A positive pregnancy test then a week later you started to bleed like period had an ultrasound at the emergency room they said show but blood came back positive?

Possible Causes of Bleeding After a Positive Pregnancy Test:

- _Implantation bleeding_: This is light spotting that can occur when the fertilized egg implants in the uterine wall. It usually occurs around the time of your expected menstrual period.

- _Chemical pregnancy_: This is the term for a very early miscarriage, which occurs before the pregnancy sac is visible on an ultrasound. Chemical pregnancies are common and may cause light bleeding and cramping.

- _Ectopic pregnancy_: This is a type of pregnancy that occurs outside the uterus, such as in a fallopian tube. Ectopic pregnancies can be dangerous and require medical treatment.

- _Subchorionic hemorrhage_: This is a type of bleeding that occurs behind the placenta. It can be caused by various factors, such as trauma, infection, or placental abnormalities.

- _Placental abruption_: This is a condition in which the placenta separates from the uterine wall before delivery. It can be a serious condition and may require medical treatment.

Blood Work and Ultrasound Results:

- _Positive blood test_: A positive pregnancy test indicates the presence of the pregnancy hormone human chorionic gonadotropin (hCG) in the blood. However, it does not necessarily mean the pregnancy is viable or developing normally.

- _Ultrasound showing a sac but with bleeding_: An ultrasound may show a pregnancy sac, which is a fluid-filled structure that surrounds the developing embryo. However, the presence of bleeding can be a sign of various underlying issues.

Recommended Steps:

- Follow-up Care: If you have experienced bleeding after a positive pregnancy test, it's important to seek prompt follow-up care with your healthcare provider.

- Additional Tests: Your provider may recommend additional tests, such as repeat blood tests or ultrasounds, to monitor the status of the pregnancy and identify the cause of the bleeding.

- Medical Treatment: The appropriate medical treatment will depend on the underlying cause of the bleeding and may include medications, rest, or surgical intervention.

Remember that each pregnancy and situation is unique. Your healthcare provider is the best source of personalized advice and guidance regarding your specific circumstances.
