Conception And Implantation

 When counting from the first day of the last menstrual cycle, which is around two weeks before conception actually takes place, a typical pregnancy typically lasts 40 weeks. Pregnancy's three trimesters last approximately 12 and 13 weeks each.. Both the developing fetus and the pregnant woman's body undergo changes during each trimester. Following the union of the sperm and the egg (conception), the resulting cells begin to multiply rather fast and go down one of your fallopian tubes to your uterus. Blastocysts are this collection of cells that are developing quickly. This little bundle of cells must connect to or implant itself into the uterine wall once it has reached the uterus. This stage, known as implantation, causes the release of more of those pregnancy hormones.

Depending on when you ovulate, implantation happens anywhere from 6 to 12 days later. Most frequently, it happens 8 to 9 days after fertilization. So, depending on when you ovulated and whether conception took place early or late in the ovulation window, the precise date of implantation may vary. The symptoms and signs of implantation are recognized by some women. Light bleeding, cramps, nausea, bloating, painful breasts, headaches, mood changes. Some of the symptoms that could be present are quite similar to PMS, so you might think they are just signs that your period is on its way. In addition, the majority of women are indeed pregnant while showing no evidence of implantation.
