Endometrium is the lining of the uterous, they are talking about fertilization, or more than likely fertilization with the help of a clinic, and doctor. The zygote is what the egg is after it has been fertilized and the two hapliod cells or egg and sperm becom diploid cells and now have a whole DNA or genetic code.
the zygote journey to implantation site is approx. 90 day

Implantation
The blastula is a stage of growth of a fertilized animal egg. It has about 128 cells, and follows the formation of a blastocyst by the "morula" stage (it precedes implantation in the endometrium).
Implantation is the process of the embryo embedding in the endometrium.

No, I'm afraid not. If your period has started, that means that the endometrium has started to degrade and pass out of the body via the vagina. The endometrium is where the fertilised egg would implant, without it implantation cannot occur.
zygote divides by mitosis as it travels along the oviduct to the uterus where implantation takes place. The zygote developes into embryo and placenta
