The simple answer is no, you cannot feel the moment of conception itself, because it’s a microscopic event.
However when is anything in pregnancy ever simple?
What is conception?
Conception (also known as fertilization) is when the sperm meets the egg inside the fallopian tube. This can take as long as 5-7 days after sex, depending on when the woman ovulates.
Implantation occurs when the fertilized egg travels down the fallopian tube and implants into the lining of the uterus.
From the moment of implantation, the woman’s body begins to release a hormone called HCG (Human Chorionic Gonadotropin).
However there can be as long as a 3-7 day period between when the egg is fertilised and when it travels through the fallopian tube to implant in the uterus.
All up this means it could take anywhere from 3-14 days for the egg to be fertilised and make the journey to implant into the uterus.
Why would a woman think she felt conception?
There is no direct scientific evidence that it’s either possible or impossible to know soon after you’ve conceived. For those women who believe they knew the exact moment, it could be the release of hormones that begins within moments of the egg’s fertilisation. Sensitivity to these hormonal changes may be a possible explanation as to why some women ‘just know’.
