Discovering blood when you think you might be pregnant can feel unsettling. It is natural to wonder if everything is okay or if the spotting means something is wrong.
The truth is that light spotting during early pregnancy is fairly common. In fact, 16-25% of all women experience bleeding in the first trimester. The bleeding can range from spotting to very heavy. The blood can be pale pink, bright red, or brown.
Read on to learn more about possible reasons for bleeding during the first trimester of pregnancy.
First Trimester Bleeding Could Possibly Be Implantation Bleeding
What is implantation bleeding? A fertilized egg attaches to the soft lining of a woman’s uterus, where it continues to grow during the whole pregnancy. Some women notice light spotting during this time, and that is why it is called implantation bleeding. This usually occurs around the 8th week of pregnancy. Implantation bleeding is very light bleeding that lasts for a few days and is noted when wiping or lightly on the underwear.
First Trimester Bleeding Could Possibly Be Related to Blood Near the Fertilized Egg
There are other reasons a woman may bleed during the first trimester of pregnancy. The most common reason for first trimester bleeding is a subchorionic hematoma, or a small collection of blood near the fertilized egg. As a woman’s hormones change during pregnancy, there are extra blood vessels that sit on the surface of the cervix, which is the opening to the uterus. Any disruption to this area, including a vigorous bowel movement, can cause light bleeding.
First Trimester Bleeding Can Sometimes Occur After Sex
About 9% of women note spotting after sex. The cervix is very tender and sensitive during pregnancy. If spotting is noted after sex, please stop until you discuss further with your doctor.
Other Possible Causes of First Trimester Bleeding
A vaginal infection, including a yeast infection, can irritate the vaginal wall and produce light bleeding until the infection is treated. Other reasons for bleeding could be a polyp on the cervix or you could be pregnant with multiple babies.
First Trimester Bleeding Causes That Require Prompt Medical Attention
Sometimes, bleeding can also be a sign of a more serious condition. And while these situations are less common, they do require prompt medical evaluation. One is an ectopic or molar pregnancy.
- Ectopic means the fertilized egg attaches outside of the uterus, usually in the fallopian tube.
- A molar pregnancy is considered a false pregnancy. Instead of a fetus growing, it is just a growth of abnormal tissue.
A second more serious reason for the bleeding could be miscarriage. However, half of the women who bleed during the first trimester have a healthy pregnancy.
When Should You Seek Medical Care For First Trimester Bleeding
Contact your healthcare provider if you experience heavy bleeding, bleeding that continues to get heavier, severe abdominal pain, pain only on one side of your abdomen, passing large clots or tissue, dizziness or fainting, or shoulder pain along with the bleeding. Even if your bleeding is light, do not hesitate to reach out to your doctor if you are concerned.
Caring For Your Body During First Trimester Bleeding
There are some things you can do to care for yourself at home during your bleeding. The first is to track your pad usage. This will help your provider understand how much bleeding you are having. Limit strenuous exercise for a couple days after bleeding has stopped, and avoid sex as it can make bleeding continue or worsen. Always do your best to stay hydrated and rest on your side.
