implantation signs

Implantation bleeding and spotting happens within 1-2 days after arrival of the blastocyst in the uterus, usually around 9 days after ovulation (dpo), with a range of 6-12 days. At that time, the blastocyst is barely visible to the naked eye, probably smaller than the dot above the letter "i". Once implantation happens the blastocyst becomes the "embryo".

Trying to conceive (TTC) and getting pregnant can sometimes be more difficult than expected. While you probably got many lessons in high school and college about how not to conceive, no one gives you lessons on how to conceive and improve your chances of getting pregnant until you're ready to try or have already been trying.

What Is Implantation?

ImplantationQ: What is implantation? What are signs that implantation has occurred? What is happening when implantation bleeding and spotting occurs?

Implantation happens on average 9 days after ovulation, with a normal range of 6-12 days. Some people have suggested that there are some BBT temperature charts which may show signs of implantation such as a triphasic BBT curve (a rise to a third level of temperatures) or an "implantation dip" (a one-day decrease in temperatures about a week after ovulation).
