Your menstrual period isn’t due yet and it’s been less than a week since you have conceived. By the end of this week, the fertilized egg may be implanting into the wall of your uterus. When this happens, you may notice some spotting and possibly mild cramping as well. Not every woman experiences this, but occasionally it does occur. This spotting is often called “implantation bleeding” or “implantation spotting” and it generally happens just before you’d expect your period to begin (approximately 3-12 days following conception), but is lighter than a normal period and typically a different color. This spotting may make you think your period has just arrived early, but in fact could be the first sign conception has taken place.

A few women who are very in-tune with their bodies, especially those who are trying to conceive, may start noticing breast changes as early as now. Sensitive, sore nipples and swollen breasts are not uncommon as one of the very first symptoms of early pregnancy. This is due to all the many hormonal changes happening within your body.

Besides possibly experiencing a little spotting at the time of implantation and maybe tender breasts by the end of this week, your body probably isn’t letting you know you’re pregnant quite yet. There are no obvious physical changes, even though there’s a lot going on inside you. The majority of women have no idea they’re pregnant at this point, because their period won’t be late for another week or so. A few very sensitive pregnancy tests may be able to detect the tiny amount of human chorionic gonadotropin (hCG) that is already being produced by your body by the end of this week, but almost all would give a false negative if taken now. To get the most accurate result, it is best to wait until your period is at least one day late.
