I know it takes 9 months pregnancy for the baby to be born?

Question

What if a couple has sex on January 31, will the female get pregnant right away. How many hours? So if the couple has sex on January 31 does that means the baby would be born on October 31? Help me out because im curious.

Answer 1

you can't very reliably predict a due date. Babies are born when they are good and ready to be born.

Calculating pregnancy due date
The due date is usually computed from the first day of the last regular period. In the calendar, this can be figured by taking that date, subtracting three months, and adding seven days. Figuring due dates accurately is tricky and has very important implications for your pregnancy. If your due dates are figured incorrectly, you

may be pressured into all kinds of unnecessary interventions at 'term' when you are not really at term at all.
A
common result is to be pressured into a pitocin induction of labor, which when done on an unripe cervix has a very high failure rate, can be quite painful, and often ends in a C-section for "failure to progress." In addition, babies who are induced due to incorrect dating may be born earlier than nature intended, and can have immature lungs and other problems, needing special care.

While most women know what a due date is, they are often less certain of what it means and how it is determined. The old-fashioned term "estimated date of confinement" (or EDC) is simply another term for due date. In the years before we had our current technology, the only way to determine this date was by calculating 280 days (40 weeks) from the start of the last period. Keep in mind that conception does not actually occur until two weeks after the last menstrual period (LMP), which means that a full term pregnancy really lasts 38 weeks, not 40.

A simple method to identify your due date is to start with the first day of your last menstrual period. Subtract 3 months and add 7 days to this date. For example, if your last period began on June 7th, your due date would be approximately March 14th. This method is most accurate in determining your due date if you are certain of the date of your last period, and your cycles are approximately 28 days long.

A typical pregnancy lasts, on average, 280 days, or 40 weeks - starting with the first day of the last normal menstrual period (LMP) as day 1. An estimated due date (EDD) can be calculated by following steps 1 through 3: First, determine the first day of your last menstrual period. Next, count back three calendar months from that date. Lastly, add one year and seven days to that date. This method is referred to as Naegele's Rule and is based on a normal 28-day menstrual cycle. Naegele's Rule is based on the belief that human gestation is 10 lunar cycles (nine months plus seven days), not on empirical data. With Naegele's Rule, a pregnancy lasts 40 weeks after LMP, or 280 days. This allows for 2 weeks of 'pregnancy' in the beginning when you are not really pregnant (the time between LMP and ovulation/fertilization). If considering from conception instead of LMP, pregnancy in this system lasts 38 weeks or 266 days. It is extremely important to know whether a system is referring to dating from LMP (date of last menstrual period) or from conception. To predict your due date using Naegele's Rule, take the date of your last LMP and add 7 days. Then count back 3 months to get your due date. For example, if your LMP was June 22, adding 7 days comes up with a date of June 29; subtracting 3 months then comes up with a due date of March 29th.

Dr. Konald A. Prem at University of Minnesota Medical School has another formula that works for women who ovulate later than day 14. In Prem's rule, the due date is taken from the first day of overall thermal shift minus 7 days, then plus 9 months. This has a high rate of accuracy for women whose cycles are longer than 28 days and who can document their temperature shifts/ovulation. It may be of some limited use to women who are not charting but who have regular periods that run longer than 28 days and know about on which day ovulation usually occurs. It can also be of use if you are irregular but have not yet conceived and can start charting. If your cycles are irregular and you are not charting, this is not a good system for you.

Full-term
Refers to a full term pregnancy. Infants who are not prematurely born are considered to be full-term. The World Health Organization considers full-term any infant born after 38 completed weeks of gestation. The American College of Obstetricians and gynecologists considers full-term any infant born after 37 completed weeks of gestation.

Full-term infant
Baby born between the 38th and 42nd week of pregnancy.

When does implantation take place?

One such relatively recent study tells us that implantation does not always take place on day 7 after ovulation. In fact it very rarely does. This study by AJ Wilcox (1) accurately determined the day of implantation by very sensitive pregnancy test (HCG) measurement compared to ovulation.

HCG hormone starts being produced when the pregnancy implants into the uterine lining. The findings in normal women trying to conceive included:
first appearance of HCG (implantation) occurred 6-12 days after ovulation
84% of the pregnancies implanted on days 8-10 after ovulation
early pregnancy loss increased with later implantation -
implantation early pregnancy loss rate
13% by day 9
26% on day 10
52% on day 11
86% on day 12 or more

Overall the total pregnancy loss up to 6 weeks was 25%. Now that seems very high to most people but keep in mind many of these pregnancy losses occurred so early that women often were not aware they were even pregnant. The normal early pregnancy loss rate that most women know about is 15-18% of clinically recognized pregnancies so almost 40% of all pregnancy loss is unrecognized.
When is the best time to have intercourse in order to get pregnant?

Wilcox had also performed previous work in 1995 (2) which demonstrated that pregnancy only occurs if intercourse occurs within the 6 days prior to and including ovulation. Intercourse after the day of ovulation does not result in pregnancy. The probability of conception ranged from 10% when intercourse occurred five days before ovulation to 33% when it occurred on the day of ovulation itself.

This is the data that suggests the best timing of intercourse in order to conceive is day 10, 12, 14 and 16 (in case of late ovulation) of a 28 day cycle or days -4, -2, 0, +2 in relation to expected ovulation in the case of cycles different than 28 days.

Answer 2

So which is it, 5 or 9 months? Nearly all medical gurus bear in mind a being pregnant doable (that means the fetus could survive outside of the womb at 27 weeks - that is roughly 7 months). I've heard so many versions of this story that it is rough to grasp what is BS and what is not. The variation I've heard essentially the most normally is that the start in query was once afflicted with Down's Syndrome and the mum chose to not use life help. If Hannity goes to do the story it mainly is a lovely certain bet that the variant you present shouldn't be the reality what-so-ever.

Answer 3

Not necessarily. You calculate the due date by one of two ways. Count 40 weeks from the first day of the last period. Or count back three months, then add 7 days. For example, my last period was June 3rd. I count back three months to March 3rd, then add 7 days, which makes me due March 10th. Counting 40 weeks also gave me the same due date.

Answer 4

Our journey is there is an hassle-free of 40 weeks, yet each and every mom is diverse. it is likewise very confusing for any healthcare expert to pinpoint the time because of the fact he can no longer tell precisely once you conceived. We have been happy our 4 infants have been born somewhat early and have been 5.2 to 6.5 lbs. They introduced greater hassle-free, their Apgar scores have been 10, and it replaced into much greater efficient on my spouse because of the fact her exertions purely lasted some hours.

Answer 5

if you want to find out your due date-just type in 'due date calculator' in the yahoo search-you will get some sites that can give you an approx. date.

pregnancy is 40 weeks (give or take 2 weeks) from the first day of your last period-not the day you had sex.

Answer 6

Our bodies and cycles don't know how to calculate 9 months exactly. We usually deliver between 36 to 42 weeks after gestation. It's an estimate.

Answer 7

You don't necessarily get pregnant right away. The sperm could live up to at least 24-48 hours. So anywhere in that time frame could be when you get pregnant, but you're not always (obviously) guaranteed to get pregnant.

Answer 8

40 weeks is not the same as 9 clean months. Work it out.

Answer 9

It isn't usually counted from the exact day you had sex. It's counted from the last day of your period. And you didn't include that, so sorry can't help you.

Answer 10

just write down the time and keep up with it that way
