If conception occurred, implantation (when the fertilized egg attaches to the uterine wall) typically happens seven to ten days after ovulation, but it can happen a few days earlier or later as well.
There are some signs of implantation or successful conception that may be seen on your chart but all of them can occur with or without pregnancy. You can also be pregnant and see none of these signs on your chart. There is thus really no way to know if they are related to implantation while they are happening, though they occur with greater frequency on pregnancy charts. Some possible signs of implantation or successful conception are:
While these signs may offer clues as to whether or not you have an increased probability of pregnancy, they are really not a reliable way to gauge whether or not you may be pregnant. You can experience any of these signs and be pregnant, or not pregnant, just as you can experience none of these signs and be pregnant or not pregnant. Keep this in mind when you are scrutinizing your chart while you wait to take a pregnancy test.
While you can be cautiously optimistic if you do see these signs (if you have well-timed intercourse during your fertile time) there is no way to really know if you are pregnant before you can reliably test for pregnancy. Likewise, if you do not see these signs (and you have well-timed intercourse within your fertile time) you need not give up hope before the end of your cycle. Many women do not experience implantation signs or very early pregnancy signs at all.
