The timing of implantation depends on ovulation and fertilisation. Successful implantation is considered the start of a pregnancy. Implantation refers to the process of attachment of the embryo to the lining of the uterus. Here is all you should know about implantation bleeding. It shows implantation in the uterus and is one of the early symptoms of pregnancy.

The process of conception can seem daunting (and exciting), but know that as long as you regularly have sex, your chances of getting pregnant within a year are generally high.ДЄll rights reserved. Implantation is a key milestone of the pregnancy journey, and understanding how and when it occurs can help you conceive and test. The causes of failure to implant are not always known but are thought to be a combination of uterine abnormalities (such as fibroids, polyps, or infection) and/or embryonic abnormalities (often chromosomal) and failure of the crosstalk between embryo and uterus due to the same hormonal abnormalities.

When this happens three or more times in failed (IVF) attempts it is called recurrent implantation failure (RIF). However, when using fertility treatments, you may know when an embryo does not successfully implant. If this happens during a typical cycle of trying to get pregnant, you will likely have no way of knowing. While you canвЂ™t control when or where an embryo implants an issue that can occur is the failure of the embryo to implant. When the egg is not within the confines of the uterus, the pregnancy is not viable. Some of these pregnancies also occur in places such as the ovary, abdomen, or cervix. This is considered an ectopic pregnancy or tubal pregnancy because many of these pregnancies occur in the Fallopian tube. Occasionally, implantation occurs outside of the uterus.

Most often implantation of an embryo happens without a hitch, but occasionally a problem may occur.

Typically, signs or symptoms of pregnancy do not occur immediately following implantation.ДЄlthough not always the case, most women start to experience early pregnancy symptoms such as nausea, fatigue, and breast tenderness around the time of their missed period. This is commonly referred to as an implantation dip and can indicate pregnancy if you chart your BBT. If you are tracking your basal body temperature (BBT) on a fertility calendar, a brief, one-day drop in BBT can occur during implantation.

You may not have any specific signs or symptoms to indicate that implantation has occurred, but a small number of women experience a phenomenon called implantation bleeding around this time. Testing this early is usually something that is not recommended unless there is a very specific reason, as false-negatives can occur. In the very early stages of pregnancy, there is likely very little HCG in the urine because there hasnвЂ™t been enough time between implantation and testing for it to build up in the body.ДЄ pregnancy that has implanted four days prior to the expected start of your period is just beginning to send signals to the body. This is why the levels of HCG in the body will vary depending on how long after implantation you take a pregnancy test. Pregnancy tests are very specific about their timing because they test for the presence of a hormone called human chorionic gonadotropin (HCG).Д«ecause HCG is produced by a developing placenta, the body cannot produce it until after implantation happens. Implantation itself usually occurs between six and 10 days after the egg is fertilised. The fertilised egg then travels the remaining way to the uterus, a journey that takes several days. Sperm then breaks through the barriers surrounding the egg to fertilise it. ThatвЂ™s because sperm can live for four to seven days inside the female body and meet up with an egg making its way through the Fallopian tube to the uterus.
