Implantation Cramps and Bleeding – Your First Sign of Pregnancy

You’re attempting to get pregnant, and a week or so after your ronde-vous with your significant other, you  experience some unusual cramping. Is it time to celebrate and go out and buy some baby clothes?

The implantation of a fertilized egg

Can occur three to twelve days post ovulation, but most often occurs between seven to ten days. After the egg is released from the ovary during ovulation, it is propelled through the Fallopian tube hairlike cilia. The egg becomes fertilized following ovulation in the Fallopian tube when the sperm is released prior to ovulation.

The fertilized egg is now called a zygote, and takes about 1-2 days to travel down the Fallopian tube to enter the uterus. Once there, it burrows into the uterus lining.

Pregnancy test

A woman could easily miss these early implantation signs, if they occur at all. Obviously the best way to detect a pregnancy is to wait a little while longer when a pregnancy test would be valid. But, the following are the various signs of implantation:

Implantation Bleeding

Some women experience a light bleeding that occurs when the zygote implants into the uterus. This bleeding is pinker than a normal period but could be confused with menstrual bleeding because it can occur at that time, although usually a few days to a week before the period is normally due.

It is generally very light brown or pink, and not bright red. Early pregnancy cramping can be normal in the beginning stages, so be sure to not confuse this with a period. Taking a pregnancy test the first day after the day your period would start will determine pregnancy or not. Only about 20%-30% of pregnancies result in implantation bleeding, so do not be concerned if you do not experience this.

Pregnancy Implantation Cramps/Ovulation Cramps

Implantation can cause light cramping before the period occurs, that is different from a menstrual cramp. This cramping can occur on one side of the body or the other, possibly due to which side the egg is implanted on. This cramping may occur only for a couple hours or a few days, and may occur more at night. Cramping during early pregnancy is common, but when it occurs before the period would start, it is maybe a first pregnancy sign.

Basal Body Temperature Changes

Implantation can cause a slight drop in basal body temperature, then arise. You may notice this if you have been monitoring your basal body temperature for ovulation.

Using these signs of implantation to determine pregnancy is not a good idea. The only sure way is to use a pregnancy test at the right time. After the zygote has implanted, the body begins releasing the hormone HCG, which is known as the pregnancy hormone.

Pregnancy tests detect this hormone, but it usually takes until the first day after the period would start for it to build up enough to be detected.
