Pregnancy is the fertilization and development of one or more offspring, known as an embryo or fetus, in a woman's uterus. In a pregnancy, there can be multiple gestations, as in the case of twins or triplets. Childbirth usually occurs about 38 weeks after conception; in women who have a menstrual cycle length of four weeks, this is approximately 40 weeks from the start of the last normal menstrual period (LNMP). Human pregnancy is the most studied of all mammalian pregnancies.
The term embryo is used to describe the developing offspring during the first 8 weeks following conception, and subsequently the term fetus is used henceforth until birth. 40% of pregnancies in the United States and United Kingdom are unplanned, and between a quarter and half of those unplanned pregnancies were unwanted pregnancies.
In many societies’ medical or legal definitions, human pregnancy is somewhat arbitrarily divided into three trimester periods, as a means to simplify reference to the different stages of prenatal development. The first trimester carries the highest risk of miscarriage (natural death of embryo or fetus). During the second trimester, the development of the fetus can be more easily monitored and diagnosed. The beginning of the third trimester often approximates the point of viability, or the ability of the fetus to survive, with or without medical help, outside of the uterus.
Another night to say:
Things are about to change, is it forever?
Another game to play
When we hare a world together
Open your eyes and believe me
You gotta live and dream again
Still catching the sun as you're gliding
Uohoh!
Ev'ry night you take my heart
Into the stars and ev'rywhere
I dream to see you back
When I return but you're not there
Ev'ry night I feel you smile
And I can't stop be similing too
So tell me how, today
I'll find the way to be with you, every night
Pictures in black and white
Bridging you from the past into the future
I want you now to try
