Question for everyone who has had a BFP

Post by angelamw »

Hi, I have got a theoretical question for anyone who has had a BFP, at what point are you actually pregnant. I was asked this on Saturday by one of my friends. We are now 4dp2dt. I supose we are now pregnant as the embrios are inside me. It is a really wiered feeling after waiting so long. I guess it comes down to when you believe life bgins. I would love to hear your thoughts on this.

Ang,

Many people beleive it begins once implantation occurs.

I personally beleive that life begins as soon as the sperm fertalizes the egg. The embryo then starts to divide - Hence - a life form!

I think ur actually pregnant tho, when the embies implant and attatch themselves to you ...

If "4dp2dt" means 4 days after a transfer of day 2 embryos, then those embryos are only able to attach today or tomorrow.

Embryos are surrounded by a "shell" called the zona pellucida. About 5 or 6 days after fertilization the embryos will form into blastocysts, where the cells are differentiated for the first time. An inner mass of cells will become the fetus, while the surrounding cells (trophectoderm) will form the placenta and gestational sac. About a day after that, they can "hatch", by breaking out of the zona pellucida. Only then can they begin to attach, assuming they continued developing for those 4 days, and assuming the endometrium is receptive at the proper time.

When that occurs, you are pregnant. However, it takes another week, plus or minus, before they will produce a detectable level of hCG to be picked up in a blood or urine test. That test is for beta hCG (part of the very large hCG molecule), and is sometimes called a "beta test". Until then, you will not know.

I want to know when exactly the Beta HCG is in the serum..I mean how many days after embryo transfer...I am confused about the terms and days..WE have 3 day embryo transfer and we tested 10 days after transfer and we have negative result...can it be positive later days

hi all...today we are 14. day of after 3-day embryo transfer..we have the result BFN...0,123...we are sorry...I want to write that all I get it
the embryo implant the uterine wall between 6.day and 10. day after fertilization.so the early Bhcg result you can get from the serum by biochemical machines is 7.day after fertilization..and last day is 16.day...so the fact that all the doctors tell patients about do the test after 14 days after transfer is just to cleat the hcg levels..I mean befor oocyte retrival they enjected HCG (pregnyl or like that) so it is still in the serum for 14 days....so every clinic says do the test 14 days after transfer..and there is another reality urine strip hcg tests and serum hcg level tests are different as everyone knows...so never try with urine strip tests...just if you are curious about the result do the quantitative serum (blood) test..
and I would like to thank everybody who replied my question..
and I am a medical doctor..and I am clinical chemist specialist...but I realized that dont ask a doctor..ask a patient ..because when your are in play you know more than a doctor... Am I wrong


Anyway we are thinking to try again 3 months later..I am man..and my wife is still doesnt know the result...how should I give the bad news to her..what is your advises ..and for the wekk ahaed what should we do....

and we have frozen sperms..because I am an non obstructive asospermia patient and they found a lot of sperm from my tese.and they frosen some...if we try again 3 months later what shold we use for..a new fresh tese sperms or the frozen ones...which is better...
