Morning sickness - too soon for it?
Could morning sickness occur as early as six weeks after conception?
Morning sickness can occur at any time during pregnancy but it occurs most commonly between two to four weeks after conception has taken place. In many cases it disappears after the first trimester has elapsed but it can persist in some cases right throughout the pregnancy. It is thought to be due to a build up of HCG (human chorionic gonadotrophin) in the woman’s system. HCG is a hormone that is secreted during pregnancy. It is excreted in the urine and detection of this chemical in the urine forms the basis for the pregnancy test. HCG production commences at the time of implantation therefore it is possible that a woman could experience morning sickness before she has undergone a pregnancy test to confirm that she is pregnant.
