Symptoms before implantation


This subject comes up quite a lot and I thought I'd share what I found (thank you google) on the subject. For those of you that think you're going crazy because you're having symptoms before implantation and you don't think that you should be...you're not crazy!!

There are very few, if any, pregnancy symptoms before implantation, since the embryo has not begun to make hcg. However, your body does not continue *as normal*, or with business as usual. After hatching from the zona pellucida, the embryo sends a signal to the ovaries to secrete early pregnancy factor (EPF), which occurs from 1-2 days after fertilization. This EPF begins a dialogue between the embryo and the mother. It is possible, therefore, that a woman who is very sensitive, or is accutely aware of things, may have some symptoms associated with the EPF secretion, although I am not sure if this has been studied.

EPF is an immunosuppressant. Along with other substances associated with early embryos, EPF believed to play a role in preventing the immune system of the pregnant female from attacking the embryo. In humans, modern pregnancy tests detect human chorionic gonadotropin (hCG). hCG is not present until after implantation, which occurs six to twelve days after fertilization. In contrast, EPF is present within hours of fertilization. While several other pre-implantation signals have been identified, EPF is believed to be the earliest possible marker of pregnancy. The accuracy of EPF as a pregnancy test in humans has been found to be high by several studies.

Oh now this is interesting because it lowers your immune system if I'm reading that right and I currently am 11DPO and have a chest infection which started Friday (6DPO). Now obviously I could get ill at any time but I do find that link interesting so thanks for posting!
