8/11/2023 0 Comments Implantation cramps timingCan you have late implantation?Īccording to a study published in the New England Journal of Medicine, the estimated risk of early loss is strongly related to the time of implantation. While it’s possible for implantation to occur between 6 – 12 days after ovulation, implantation earlier than 8 days after ovulation is rare. In most successful pregnancies, implantation occurs 8 – 10 DPO (days after ovulation). When this happens, the egg dies and is excreted during your next period. If progesterone hasn’t adequately prepared the endometrial lining to support life, or if the blastocyst contains abnormalities, implantation will fail. This indicates that embryos are likely predestined for survival or death before even the first cell division. For the pregnancy to be viable, the cells must make contact with the endometrium and attach to the uterine wall.Īs many as two thirds of embryos fail to implant. Implantation, or the process of the combined egg and sperm cells attaching to the wall of the uterus, marks the actual start of a viable pregnancy.Īccording to recent research published in Nature Biotechnology, conception occurs much more readily than implantation, but this does not ensure pregnancy. Many people assume that pregnancy begins at conception-the moment that sperm enters the egg.Ī more accurate beginning of pregnancy would be the implantation date rather than the conception date. However, a better question might be, “When did implantation occur?” When you’re trying to get pregnant, “When did I conceive?” is a pretty common question. What does implantation mean for pregnancy? But the presence of hCG sends a signal for progesterone production to continue, and your uterine lining is maintained throughout your pregnancy. When you are not pregnant, a drop in the hormone progesterone is what causes your period to begin (progesterone is the hormone that maintains the uterine lining). HCG plays an important role in early pregnancy. This is the hormone that turns a pregnancy test positive. This attachment to the uterine lining is what allows the embryo to receive oxygen and nutrients from the mother, and continue to progress and grow into a fetus.Īs soon as implantation is complete, the embryo begins to produce the hormone hCG. Implantation is the process of an embryo attaching to the uterine lining. So while using averages like 14 days (between LMP and ovulation) and 9 days (between ovulation and implantation) will tell you when implantation tends to happen on average for women as a whole, it won’t tell you much about when implantation happened for you. The reality is that your cycle is variable and the day you ovulate won’t necessarily be consistent from cycle to cycle. Important note: The above calculations are a very oversimplified guess. *23 days = 14 (average number of days between LMP and ovulation ) + 9 (average number of days between ovulation and implantation)
