How many weeks pregnant are you at implantation?

How many weeks are you at implantation? – Implantation occurs soon, at about 4 weeks pregnant. For implantation to happen, the cells in the fertilized egg, now a morula, will continue to divide until it becomes a blastocyst. About five to eight days after fertilization, the blastocyst will have arrived, where it will begin to implant in the wall of the uterus.

What a journey! “Pregnancy tests have come a long way and can even detect pregnancy before you’ve missed your period—that can work for you and also against you. For the truest result, I would recommend testing a few days after you’ve missed your period, and with first morning urine. If negative and still no period, repeat this process every two to three days—always first thing in the morning.” -, MD, an ob-gyn and medical director of Be.

What does implantation discharge look like?

Is It Implantation Bleeding or My Period? – It’s possible to mistake implantation bleeding for a very light and early period at first. However, there are some differences to pay attention to. Although every woman’s period is different, it’s still possible to guess that it’s implantation bleeding by the color and amount of bleeding, and by where you are in your menstrual cycle, as well as by looking out for other early signs of pregnancy — more frequent bathroom trips, fatigue, and nausea (i.e., morning sickness ).

The amount of blood. Implantation bleeding isn’t heavy; it’s more like a discharge or light spotting that’s about a few drops of blood on your underwear. The color of the spotting. The blood from implantation is more of a pinkish or brown color, rather than a bright red some women normally see during a period.

What is the most common day for implantation?

Discussion – In laboratory animals, there are three phases of endometrial development after ovulation: the uterine lining is initially neutral toward the implanting blastocyst, then receptive, and finally resistant.20,21 Although specific mechanisms of implantation vary widely among species, 22 these three phases of uterine receptivity are also thought to occur in humans.2 There are no undisputed markers in humans of uterine receptivity to a fertilized ovum other than implantation itself.23,24 Given that implantation cannot be observed directly, the best indirect marker of implantation is chorionic gonadotropin.1 Its production by the conceptus begins early, with expression of messenger RNA reported at the eight-cell stage.25 The abrupt appearance of chorionic gonadotropin and its exponential rise in maternal serum or urine may not mark the very earliest steps in the implantation process, but they do mark the point at which the conceptus has successfully invaded the maternal tissue.

In our study, the couples had no known fertility problems, and none of the women were being treated with hormones. In the majority of successful pregnancies (84 percent), the first hormonal evidence of implantation was detected 8, 9, or 10 days after ovulation; the earliest time was 6 days and the latest 12 days.

The range of implantation times depends in part on the precision of the markers of ovulation and of chorionic gonadotropin. Any random errors in these measures would tend to spread the distribution of implantation times. Our measure of ovulation has been validated against the surge in the secretion of luteinizing hormone, which is a standard clinical marker of ovulation, and our marker appears to be as precise as serum luteinizing hormone.15 Our assay for chorionic gonadotropin is sensitive enough to detect low concentrations even among premenopausal women with tubal ligation, 9 so it is likely that the assay is able to detect the initial increase associated with pregnancy.

  • Still, no measure is without error, and the true biologic window of implantation may be even narrower than we found.
  • The only previous study of the timing of implantation in women with no known fertility problems reported results similar to ours.
  • In a study of 14 pregnancies ending in live births, rises in serum chorionic gonadotropin were detected as early as 8 days and as late as 12 days after the peak serum concentration of luteinizing hormone.26 More information on implantation has come from studies of patients with infertility, especially women treated by in vitro fertilization.

In one of the largest studies, implantation was reported in relation to egg retrieval for 140 clinical pregnancies in which conception occurred in vitro.27 Implantation was detected 6 to 13 days after egg retrieval. In another report of 76 term pregnancies with in vitro conception, implantation occurred as early as 7 or 8 days after egg retrieval and as late as 13 or 14 days.6 In our data from natural conception cycles, no conceptus resulting in a clinical pregnancy implanted later than 12 days after ovulation.

  • We found a strong increase in the risk of early pregnancy loss with late implantation, a finding in agreement with data from smaller studies.6,26,28,29 Pregnancies with late-implanting conceptuses may fail for several reasons.
  • The receptivity of the endometrium decreases during the late luteal phase, 1,2 and the corpus luteum is less responsive to chorionic gonadotropin by 11 or 12 days after ovulation.30 Factors intrinsic to the zygote could also be at work.

Unhealthy zygotes may develop more slowly, or implantation may be abnormal, 31 resulting in later and weaker production of chorionic gonadotropin.32 To the degree that imperfect embryos develop or are implanted more slowly, a limited window of receptivity may provide a gating mechanism that helps screen out impaired embryos.

  • The data may have implications for efforts to manipulate uterine receptivity.33,34 Some women may be subfertile because of an unusually short window of implantation.
  • There may be opportunities to increase fertility by extending the time during which implantation can occur.
  • Such interventions should be approached cautiously, however, because they may have unintended consequences with respect to the quality of surviving embryos.

In summary, implantation occurred 8 to 10 days after ovulation in most healthy pregnancies. The proportion ending in early loss increased when implantation occurred later. A refractory period after the time of uterine receptivity may provide a natural mechanism by which impaired embryos are eliminated.
