Implantation Bleeding - Causes, Symptoms and Treatment

Implantation bleeding is an early sign of pregnancy and happens right before the expected period date. It is among the common reasons for bleeding during the first trimester of pregnancy. Implantation bleeding generally occurs about 1 – 2 weeks after the egg has been fertilized in the uterus. The time of implantation bleeding is around 1 week after ovulation and a few days before the female has her expected period.

Implantation bleeding is generally spotting or light bleeding, much less than a normal period flow. This bleeding may occur just once or may last for a few hours. To the maximum, implantation bleeding can last up to 3 days. 

Implantation bleeding may be pink or brown in color and thus is easy to differentiate from the bright red bleeding of periods. A female usually does not need to use a pad or a tampon in case of implantation bleeding as the bleeding is very less, just like spotting.

Implantation Bleeding Symptoms

Implantation bleeding is one of the earliest pregnancy symptoms which can be easily identified by the female. As implantation bleeding occurs before the expected period date, many females confuse implantation bleeding with an early period or spotting. Symptoms of implantation bleeding include- 

  • Light bleeding or spotting which may look like pink or brown discharge
  • Abdominal cramps 
  • Vaginal discharge (thick, clear, white, or yellow in color)
  • Bloating
  • Sensitive or tender breasts 
  • Nausea 
  • Headache 
  • Mood swings 
  • A decrease in basal body temperature (Implantation dip)*

(*Implantation dip– It is a minor drop in the body temperature that occurs about 7-10 days after ovulation due to an increase in the progesterone hormone.)

The above-mentioned symptoms can also be those of PMS (Premenstrual Syndrome) or ovulation. So having such symptoms does not guarantee that you are pregnant. On having such symptoms, consult a gynecologist or take a home pregnancy test to confirm pregnancy.

Implantation bleeding is totally normal and needs no medical attention. But at times, such light bleeding or spotting can be due to other conditions like irritation of the cervix after a pelvic exam, sexual intercourse, or vaginal infections.
