is the carrying of one or more offspring, known as a fetus or embryo, inside the uterus of a female human. In a pregnancy, there can be multiple gestations, as in the case of twins or triplets. Human pregnancy is the most studied of all mammalian pregnancies. Obstetrics is the medical field that studies and treats pregnant patients.
Childbirth usually occurs about 38 weeks from fertilization, i.e., approximately 40 weeks from the start of the last menstruation. Thus, pregnancy lasts about nine months, although the exact definition of the English word “pregnancy” is a subject of controversy.
One scientific term for the state of pregnancy is gravid, and a pregnant female is sometimes referred to as a gravida. Both words are rarely used in common speech. The term embryo is used to describe the developing human during the initial weeks, and the term fetus is used from about two months of development until birth. A woman who is pregnant for the first time is known medically as a primigravida or "gravida 1", while a woman who has never been pregnant is known as "gravida 0". Similarly, the terms "para 0", "para 1" and so on are used for the number of times a woman has given birth. If a woman has never given birth, she is referred to as nulliparous.1
In many societies' medical and 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.

The condition of being able to make twice as much money in the porn industry due to supply and demand.
Thanks to Sheila getting knocked up, she landed one of the lead roles in in Fat Pregnant Anal Whores XVII and made enough money to stay high for a month.

1. A state a woman may find herself in after having unprotected sex with a man. Involves a child growing within her body and can be discovered by the absence of menstruation. May cause illness.
2. Bloated, held out, prolonged.
I'd also like to say something to all the men out there who think that getting a girl pregnant is a death sentence!
Being pregnant is a wonderful and painful experience that you'll never have, so just shut the hell up about your selfish views. Women don't trap men by getting pregnant. It's not their choice!

1. Jenny: It's been two months since my last period!
Katy: Oh no! Have you and your man had unprotected sex recently?
Jenny: Yeah, a month and a half ago.
Katy: Oh my god, Jenny, you have got to be pregnant.
2. After making his abrupt statement, Jake hung his head wearily. Neither of the boys spoke, and a pregnant silence filled the small room.
