There are many synonyms for the term "early pregnancy". Some options include "gestational period", "conception phase", "first trimester", or even simply "the beginning of pregnancy". In the medical field, doctors may refer to this time as the "embryonic stage" or "implantation period". Women who suspect that they may be in the early stages of pregnancy may refer to it as the "two-week wait", or "TWW". No matter what terminology is used, the early stages of pregnancy are important for monitoring the health of the mother and the developing embryo, and should be taken seriously by both medical professionals and expectant mothers alike.
