Why you could have symptoms before implantation

I've been searching for this info for a while.

The syncytiotrophoblast is the outermost layer of the fertilized cells and is thicker and in contact with uterine spaces. It becomes a syncitium (layer of nuclei and cytoplasm without lateral cell borders) and is termed the "syncytiotrophoblast".

Wikipedia confirms it (if you trust Wikipedia as a source)

http://en.wikipedia.org/wiki/Syncytiotrophoblast

The syncytiotrophoblast secretes progesterone in addition to human chorionic gonadotropin (hCG) and human placental lactogen (HPL); hCG prevents degeneration of the corpus luteum.

Implantation stages:

The trophoblast differentiates into two different cell masses, shortly before it comes into contact with the endometrium:

  • the outer syncytiotrophoblast (ST)
  • the inner cytotrophoblast (CT)

Very interesting! Thanks for posting that. The term Chemical Pregnancy to me has always bothered me greatly because of this!! How can we have HCG without implantation?? This sort of helps to explain it though.

That was bothering me too! If there was no HCG before implantion, what makes a CP different from a miscarriage. If what I posted is accurate, a CP is much more logical.

Do a search for "early pregnancy factor." My million dollar idea involves designing a cheap, accurate test for EPF. Women could know within 48 hours if fertilization had occurred. Of course that wouldn't tell you if implantation would occur, but wouldn't you buy a test that could tell you your chances of pregnancy were much higher that cycle? Wink

You bet I would. I'd rather know if we even caught the egg before I obsess for two weeks.

That was very interesting.......I wonder what is going on in there...With my son I knew the exact date when he implanted..I felt it around the same time for 2 days...it was like the egg was nestling in the uterine wall.... so that information confirms what i was feeling....:laughing4:

Holy crap, you bet your bottom dollar, I'd pay for a test that told me if the tww was worth the obsession or not!!!

I'd buy a test like that in a heartbeat!!

I definitely would too, it would possibly save a lot of heartache and obsessing time.

I don't think I'd buy that test. I am PUPO right now. I know the egg fertilized, I even have a picture of my embryo. It doesn't make the 2ww any less stressful. I think I am more obsessed now then ever. I am constantly talking to my belly, asking the little one to stick, promising to be a wonderful mother. Seems to me that while we were TTCing naturally I could "forget" about it for a few minutes/hours, but now it is constantly on my mind.

And if you knew the egg fertilized but you did not end up getting a BFP, It would make you think about so many negative things. What is wrong with my eggs, what is wrong with the sperm, maybe my lining is not good, etc...

Actually, that is part of the reason I would buy the test. It eliminates a couple of things that could be wrong. We would know our timing was right, that the sperm met the egg, the egg was able to be fertilized, etc.

Same reason why I think the test would be GREAT!!! So many people go through years of unexplained infertility, even investing in IVF only to discover that conception wasn't the issue but "old eggs" or something preventing adhesion. If you can say 100% fertilization did or did not take place, think of the years of trying, and expensive, PAINFUL procedures that could be eliminated!
