10 days after conception
Roughly 10 days after conception
The brown colour means that it is not fresh blood. It could be from implantation 4 - 7 days after embryo transfer or from an implanted embryo releasing from the uterine wall, more recently. More than one embryo was transferred. Don't stop taking the prescribed medication until a blood test confrims that there is no pregnancy.
An embryo can form in as little as 3 days but it needs 21 days at 99.5 degrees To hatch. Unfertilized eggs or eggs stored In the fridge will not form an embryo ever.
Implantation can start to occur as soon as 6-10 days after retrieval (I use "after retrieval" because embryos can be transferred on different days of development. Count the retrieval day as day 0). Five days after the retrieval a healthy embryo will have reached the blastocyst stage. Six-seven days after the retrieval, a healthy embryo will start breaking out of its hard outer shell and begin the implantation process. After the healthy embryo has implanted in the uterus it will not start secreting hCG for several more days. You will probably not be able to feel the implantation process.
8-10 for american, 10-14 days Euro dove to hatch
