Sometimes bleeding happens during pregnancy, and it is not always a signal for a woman to panic. This is a typical symptom during the first trimester. However, it is still necessary to visit a doctor because there are high risks of serious pathologies. 

bleeding during pregnancy

Bleeding at the First Trimester 

Some bleeding spots are recorded in about 20% of pregnant women at this period. This condition is caused by:

  • Miscarriage. Contact your obstetrician if you suspect a miscarriage. But we can assure you that more than 90% of women who have bleedings during their first trimester do not have a miscarriage. 
  • Implantation bleeding. It means that there is an implantation of the fertilized egg in the uterus lining. Some women may even think that they have periods, and do not even suspect any pregnancy. This bleeding may last from a couple of hours to several days. 
  • Ectopic pregnancy. The embryo implants in the fallopian tube. If it continues growing, the fallopian tubes may be burst, and it is very dangerous for a woman. 
  • Infection may also induce vaginal bleedings (gonorrhea, chlamydia, and others).

Bleeding at the Second and the Third Trimester 

In this case, it is a serious signal to concern. Go to an obstetrician right away. This condition may be caused by:

  • Placental abruption is accompanied with back pain, abdominal pain, and vaginal clots. 
  • Placenta previa happens when the placenta is too low in the uterus, and the birth canal opening is partially covered. It is rare, and occurs in 200 pregnancies.  
  • Uterine rupture happens as a result of the C-section opening during the pregnancy. It is life-threatening.
  • Premature labor. It may be a signal that your body is preparing for labors. If a pregnant woman has bleeding spots before 37th week of pregnancy, she should visit a physician.   

What to do?

Noticing any bleeding spots during your pregnancy, just take a pad and go to your obstetrician. You should also pay attention to the amount of the discharged blood and its structure (color, thickness, etc.). Do not use tampons, and do not have sex during bleedings. Any tissues passed through the vagina should be brought to a doctor.
