How long after implantation bleeding will the pregnancy hormone be present?

And how long does implantation bleeding usually last?

Just to be technically correct, HcG is produced as soon as conception happens, rising rapidly, but it cannot be detected at that point. Only after implantation can it be detected in blood or urine. So, HcG will be present even before implantation, just cannot detect it. After implantation, one needs to wait at least 2-3 days for HcG to be shown in any reasonable amount (15mIU for blood test) to show positive. For early HPT (urine test), HcG needs to reach 25mIU which can usually be reached within 5 days after implantation.

With respect to implantation bleeding, you may not get it at all, and even if you do, it doesn't always mean implantation happened that day. One can even get brown spotting from previous implantation bleeding after six weeks of being pregnant as well.

Hope that is helpful.

    Implantation bleeding only occurs in about 5% of women. It typically lasts for 1-2 days and should be a light pink/brownish color.

    Edit: As far as when HCG will be present it is different for each woman. Some can get a postive(if pregnant) test a week before their period is due while others have to wait until they are 3-5 days late. Still, with others, it can take weeks.

    Implantation bleeding is normally just a little spotting for a day or two.
    Once the fertilised egg implants in the uterine wall the body starts producing the HCG hormone (which if you are interested the HCG hormone maintains the Corpus Leutum which is the cyst that forms on your ovary once the egg is released and it is this cyst that produces the prostegene to maintain the pregnancy until the placenta is formed and functional at 8-10 weeks).
    Anyway, the HCG hormones starts to be produced immediately once implantation occurs and doubles every 2-3 days in early pregnancy.
    It should reach a level that is detectable on a urine home test about 7 days after implantation (around when your period would be due) but can be detected on a blood test a little earlier than this.

    The HCG hormone starts to be released into the woman's blood stream soon after the baby implants into the lining of her uterus (about 8 to 12 days after conception). The HCG blood level will initially start off very low (at least 5 IU/L), but then rapidly increase (doubling every 2 to 3 days), so that within a few days to a week or so, the HCG level becomes high enough to be detected in the woman's urine (at least 50 to 80 IU/L). Once this level is achieved, a urine pregnancy test will show as being 'positive'.

    The HCG hormone peaks to its highest levels between 8 and 11 weeks of the pregnancy. Then the level slowly decreases, lowering at 12 weeks and again at about 16 weeks of the pregnancy. The HCG level remains lower until several weeks after the birth of the baby. As the HCG levels lower, the maturing placenta takes over the role of producing other hormones to support the pregnancy (at around 12 weeks). HCG levels that are higher than expected may indicate a multiple pregnancy or the woman being more advanced in her pregnancy than calculated,

    First, it's good to remember that very few women have implantation bleeding. When it happens, it's usually just a tiny bit of spotting. Once the egg is implanted, your body begins to produce hCG. It will likely take 4-5 days for there to be enough to register on a HPT.

    Good luck to you!

    Actually implantation bleeding or decidual bleeding can be light to heavy. Depends on the woman. Usually with in a week of the bleeding, if that's what it is, then you should be able to test. Good luck.

    I had implantation bleeding on the day my period was due (day 30 of cylce) and it lasted 5 days for me. Like the first day of spotting but it never really got going in to a full period. I tested every day and got a positive HPT the day after the spotting stopped. Hope this helps. Good luck!
