Trying to conceive a child can be an equally exciting and frustrating time. Between the dreams of babies and round bellies is the aggravation of waiting---first for your period to end, then to ovulate, then for the appearance of pregnancy symptoms or a positive pregnancy test. Ovulation occurs approximately halfway through your cycle, leaving you a window of about a day to "catch the egg." If you are successful, you should see a positive pregnancy test around the time your next period is due. But it is possible to see signs of pregnancy up to a week before those two lines appear on the pregnancy test, if you know what to look for.
After fertilisation, the egg travels through the Fallopian tubes to the uterus, where it attaches itself to the uterine wall. This occurs about a week or so after ovulation. In the process of attaching to the wall of the uterus, some blood vessels are broken, which results in a small amount of bleeding. This blood makes its way out of the body slowly and is a brownish colour as opposed to bright red.
When the fertilised egg embeds itself within the uterine wall, it can cause bleeding and also slight cramps. Some women feel as though they are having an early period, whereas others barely notice these cramps.
Hormonal changes begin the moment the egg implants, causing a variety of other changes and symptoms. Starting at or a week after implantation, your breasts may begin to feel full, swollen and tender. Some women may not find this a particularly helpful early pregnancy sign, as PMS symptoms can also include tender breasts.
Fatigue and Nausea
Common early pregnancy symptoms such as fatigue and nausea can begin as early as a week or two after conception, thanks to the change in hormones caused by the implanted egg. These symptoms may appear at specific times of the day or last all day long for weeks.
