  • technically the placenta starts to form before you are even pregnant. That's what comes out when you have your period.

    hcg levels are detectable by blood within the first week, as soon as the next day after conception.

  • The pp is a little off. The placenta doesn't start forming til after conception. What comes out with your period is the lining of the uterus, it builds up to cushion a possible pregnancy - when there isn't a pregnancy it sheds (period), if there is a baby, it surrounds it, and cushions the sack when it forms.

  • hcg levels are detectable by a home pregnancy test as early as 5 days before a missed period (depending on the type of test you get) and much sooner with a blood test. The placenta is visible on an ultrasound around 12 weeks I believe but begins developing right away.
