There is a lot of debate about how soon implantation can happen after ovulation. So we are going to take a look at this and determine what the earliest date and the latest date your egg can implant in the lining of your uterus and still have a healthy pregnancy.

Usually when implantation occurs you experience a slight decrease in your basal body temperature, this is commonly referred to as the implantation dip. Others have noticed implantation bleeding, but that is not as common.

Once you release an egg during ovulation and it meets up with the sperm it becomes fertilized. From there it travels down the fallopian tube towards your uterus. When it arrives in the uterus it starts to attach itself to the lining.

So when does this happen? The most common is about one week or about 7 days after ovulation, but it can occur as early as 5 dpo and as late as 12 dpo. DPO meaning Days Past Ovulation.

After the egg implants inside your uterus your body then begins to release a pregnancy hormone called hCG. This is the actual start of your official pregnancy, however doctors always calculate your due date based off the start of your last menstrual period also known as your LMP.

Before the implantation occurs your body doesn't know that anything is different than what usually happens on the other months that you are not pregnant. So there is no way to experience true pregnancy symptoms before implantation takes place in your body.

You wont be able to test positive in a pregnancy test until the hCG that is released and continues to build up after your egg implants becomes high enough in level to become positive. If you take the test too early you could get a false negative.

Since it can take about a week after implantation to build up enough of this pregnancy hormone to give a positive result to your test you'd be better off waiting at least several days before you try testing.
