The embryo-to-be, now securely implanted in the lining of your uterus, is starting to develop. Although you could do a home pregnancy test this week, you may end up disappointed or uncertain because at this stage a definite result is unlikely. It can be nerve racking, wondering if an unwanted period is about to arrive and dash your hopes. Talk to your partner and share your feelings with him-he may be anxious, too.
