Implantation of a Fertilized Egg

by Teresa Shaw |

When trying to conceive, it's sometimes hard not to scrutinize every sign and symptom you feel for possible signs of pregnancy. One of the most tell tale signs of pregnancy for many women is implantation, or when a fertilized egg, or zygote, implants into the lining of the uterus. Many women ask when does implantation occur, and what are the signs of implantation?

When Does Implantation Occur?

Implantation typically occurs 6 to 10 days after ovulation, or day 20 to 24 of a menstrual cycle. However, it can happen a few days earlier or later. In an average 28-day cycle, ovulation occurs on day 14 with the first day of a woman's period being considered day 1 in a cycle. Once fertilization occurs, the egg stays in the fallopian tube for three days before entering the uterus and begins to implant itself to the uterine lining.

Find out when implantation will happen based on your last menstrual period or ovulation date with our implantation calculator.

What is Implantation?

Implantation happens when a fertilized egg attaches itself to the uterine wall. Once fertilization occurs, the fertilized egg remains in the fallopian tube for 3 days. It then enters the uterus where it gets very close to the lining of the uterus (endometrium) and begins to invade this endometrium to implant.

What are the Signs and Symptoms of Implantation?

Implantation is usually a quite gentle process with very few symptoms that can be felt or noticed. Most symptoms are usually detected or diagnosed as implantation once pregnancy has been confirmed; that is, once you realize you're pregnant, certain symptoms you might have noticed a few days prior will match up to those common to implantation.

The following are some typical signs of implantation.

Only a positive pregnancy test or a blood test performed by your doctor can confirm that you are pregnant. Don't despair if you haven't felt or noticed any of these signs of implantation. Very few women actually notice implantation, and not feeling implantation does not mean that you are not pregnant. If you think you might be pregnant, be sure to make an appointment with your doctor to confirm a pregnancy.

I've been ttc with my husband. i had bleeding around the time of my period, jan 23, for 4 days, but it was way lighter then a period. i've been sleeping a lot, and have cramps on and off. my boobs don't hurt, but they seem full, not bigger. i feel sick to my stomach, but never throw up. i took a test on the 26th and it was negative. do you think i'm pregnant?

Hi. my last menstrual cycle began on december 22, 2014, and we had unprotected sex on december 25th and the 28th. today is january 22, 2015, and i'm one day late. i did a pregnancy test and it was positive. my question is, when is it most likely that i conceived? for example, if i had unprotected sex on dec 28th, did i get pregnant right away, or would it have taken a few days for implantation to happen?

On day 20 of my menstrual cycle, i experienced spotting and cramps that lasted a couple of hours. it has been 2 days since the spotting, and i have had extremely sore breasts to the touch, and they get heavy and feel full. also, i have been sleeping all day, not even knowing i was that tired. i took a pregnancy test 2 days after the spotting. it was negative. can someone please give any advice associated with this? thanks!

If you got your period, then i would imagine that you are not pregnant.
