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.
The period from conception to birth. After the egg is fertilized by a sperm and then implanted in the lining of the uterus, it develops into the placenta and embryo, and later into a fetus. Pregnancy usually from the first day of women’s last menstrual period and is divided into three trimesters, each lasting three months.
Pregnancy is a state in which a women carries a fertilized egg inside her body.
"Before you were born I carried you under my heart. From the moment you arrived in this world until the moment I leave it, I will always carry you in my heart".
In couples having regular sexual intercourse every 2 or 3 days, and not using contraception, 84% will become pregnant within a year, and 92% within two years. The rest may take longer to conceive, and some may need help or intervention.
The optimum biological age for pregnancy is between 20-35 years of age.
The best time to get pregnant and have sex intercourse is the so-called "fertile fertility window." The fertile fertility window extends for 6 days starting at 5 days before ovulation until the day of ovulation. Your most fertile days are the 1-2 days before and the day of ovulation
When is the best time to get pregnant?
The fertile window which is the best time to get pregnant has been defined as the days of the menstrual cycle during which intercourse is most likely to result in pregnancy. This fertile window extends for 6 days starting at 5 days before ovulation until the day of ovulation. Your fertile days are the 4-5 days before and the day of ovulation, but the most fertile days are just the 2 days before and the day of ovulation.
Sexual intercourse the day after established ovulation is unlikely to improve your chances getting pregnant. and chances getting pregnant if you make love after ovulation is nearly zero.
Increasing amounts of estrogen in the cervical mucus and reproductive tract of a women approaching ovulation generally allows the sperm to live for up to 6 days.
Does timing of intercourse improve your pregnancy chances?
Studies have shown that even in women with regular cycles, ovulation can possibly happen any time, so "timing" of intercourse and trying to answer the question when is the best time to get pregnant has never been shown to significantly improve your pregnancy chances. You are probably not improving your chances of getting pregnant if you wait with intercourse until the temperature goes up or the OPK has become positive. You may already have ovulated by that time, and sex after ovulation is unlikely to get you pregnant.
Every day versus every other day?
Couples who tried to get pregnant were previously told to have sex once every other day during their fertile days. Recent studies have shown that for the average couple who is trying to conceive the best time to get pregnant is that they should make love regularly 2-3 times a week, every week because you don't know exactly when ovulation happens.
In addition, you may improve your chances if you have sex once a day (as long as his sperm are OK) during the fertile 4-5 days prior to, and the day of, ovulation. In those rare circumstances when the man does not have enough sperm (oligospermia), the old rule of once every other day still holds true.
