Should you take a pregnancy test? Medically reviewed by Holly Ernst, P. Pregnancy tests: All you need to know Pregnancy tests measure levels of a specific pregnancy hormone. Implantation happens very early on in pregnancy, soon after the female egg cell has been fertilized by sperm in the fallopian tubes.
The fertilized egg then travels down the fallopian tubes, transforming from a single cell into a ball of multiple cells. This collection of cells then implants into the uterus lining. Usually, implantation occurs eight to nine days after ovulation when the egg cell is released from an ovary.
However, it can happen anywhere between six to twelve days after ovulation. Interestingly, while many methods of hormonal birth control work by stopping ovulation such as the hormonal IUD or the pill , some forms of birth control also work by preventing implantation from happening such as the copper IUD.
In fact, you might not realize implantation has happened - and the first sign of pregnancy might be your missed period. However, some women may experience cramps around implantation. These feel different to period cramps. They are described as being less intense, with a prickling, pulling or tingling sensation. Some women also experience ovulation pain , which happens around ovulation, preceding implantation by about a week.
These include:. As well as the symptoms listed above, you may experience a type of spotting called implantation bleeding. Implantation bleeding is caused by the fertilized egg coming into contact with blood cells in the uterus lining as it implants into the uterine wall.
Since the symptoms of PMS are also similar to those in early pregnancy, this can make things more confusing. There are a couple of subtle differences to help us tell implantation bleeding and menstruation apart….
However, since some women may experience very light periods, it can make it harder to tell the two apart. If you get implantation bleeding, it should occur around a week after ovulation, before your next period is due. Shorter and lighter than the average period, implantation bleeding usually lasts about one to three days. If you experience heavy bleeding or clotting , or have any concerns about your reproductive health, we always advise you to contact your healthcare professional.
During the second half of the menstrual cycle, a woman's temperature starts to rise and goes up about 1 degree at the time of fertilization, where it remains elevated throughout her pregnancy. If your temperature drops back down, it could mean that your period is on its way, implantation didn't occur and you're not pregnant. Implantation is an important but easy-to-miss event. Because it can cause light spotting, some women mistake it for their menstrual cycle. If your period doesn't come and you are wondering whether or not you are actually pregnant, take a home pregnancy test or see your practitioner for confirmation.
