Signs & symptoms of implantation

Updated July 19, 2017

If you are trying to get pregnant, the two-week wait between when you're most fertile and when you can take a pregnancy test can seem like months. You might be looking for signs and symptoms of pregnancy to pass the time. Implantation is the process of a fertilised egg attaching to the uterus, and it often provides the first clues of pregnancy.


Every month, your ovaries release an egg into the Fallopian tube where it can be fertilised with sperm. The fertilised egg then travels to the uterus and attaches to, or implants into, the uterus. This process of implantation can produce symptoms that can provide a woman clues she is pregnant. Implantation usually occurs about nine days past ovulation, but can happen as early as six days and as late as 12 days past ovulation.

Bleeding or Spotting

Light bleeding or spotting can occur during implantation. According to, implantation bleeding occurs in about 30 per cent of pregnancies. Implantation bleeding is often light pink or light brown and many women notice it when they are wiping after using the bathroom. This spotting is light and is the result of the fertilised egg, or embryo, burrowing into the uterus lining.

Cramping and Ovulation

Some women also note cramping during implantation. This sign of implantation is sometimes confused with menstrual cramps as some women suffer from menstrual cramps days before starting their periods.

Basal Body Temperature

If you have been charting your basal body temperature, you may notice a temperature shift after implantation. Basal body temperature is a woman's resting body temperature, taken at the same time every day, before a woman even gets out of bed. A woman's basal body temperature will rise significantly (about 0.4 degrees Fahrenheit) after ovulation. The temperature generally stays elevated until the next menstrual cycle starts. When implantation occurs, there will be a one-day drop in basal body temperature. Be sure to use a Basal Body thermometer to track slight temperature changes.


Because implantation can happen around the same time that your next menstrual period should be starting, it is sometimes confused with a period. Many of the symptoms of implantation are symptoms of impending menstruation. In addition, these symptoms are not definitive. Experiencing any or all of these symptoms does not necessarily mean implantation has occurred. These signs are not foolproof; only a pregnancy test will tell you for sure if you are pregnant.
