WLAB, scroll way back to where Diamond and I were the only ones talking in this forum (about six weeks ago) where we talked about the effects of both progesterone and hCG on the early stages of pregnancy. I uploaded some stats on levels. Both these hormones take off from the fifth day after fertilisation and escalate dramatically every second day all the way through to the 12th week and then they both drop away.

Also, review my post last week on anatomy of a pregnancy, which explains cell division from day 1-6 (fertilisation to implantation). If the blastocyst doesn't implant on the 6th day after ovulation, it won't survive. It needs progesterone to feed off until a placenta is formed and an umbilical cord is established.

I note you place a lot of importance on seeing spotting as a sign of implantation. This doesn't happen for most women, so not seeing it means nothing. If your mum is still around have a talk to her about her experience when she was pregnant. I've found my mum's memories invaluable and with the little success I've had, I've noticed my experiences are bascially the same.

:-)
