Pregnancy comes with enough challenges as it is. Calculating how far you are in terms of weeks can be a daunting task. Most women calculate their pregnancy by months while doctors calculate it by weeks. Women calculate by months because it is the easiest way to know how far gone you are. So, how long is pregnancy in weeks?
If you missed your period in January, you naturally assume your due date is somewhere in October. The calculations are usually correct bearing in mind that nobody actually knows when exactly you got pregnant. Knowing when you ovulated and the egg became fertilized is left to estimation. Even the doctors or midwives use the estimation method.
Going by your menstrual cycle, the doctors are able to estimate your ovulation dates. Once the egg becomes fertilized, it is implanted in the uterus. There is no known method to state when the fertilization actually took place. Calculating your due date starts with the first day of your last menstrual period. From here, you add the nine months and one week.
This should be your due date but it’s imperative to note that only a small percentage of babies are born on their due date. They are either a few days early or a few days late. Using months to calculate your due date makes it easier to know the trimester of your pregnancy. The first three months should be your first trimester and so on.
Calculating your pregnancy by weeks is a little bit tricky but considered the official way by most doctors. Each month consists of four weeks and seven days each. A normal pregnancy term takes 280 days if you start to calculate from the date of your last menstrual period. Going by the calculation, the pregnancy will take about 40 weeks which is ten months.
If you calculate your trimester using weeks, you will find that the first trimester starts from the first week to about the 13th week. In months, it is about 3months and one week. For most women, it becomes difficult to count by weeks as it is more confusing. They often wonder if it is ten months or nine months.
A normal pregnancy is about 40 weeks, but any baby born the 38th week or the 42nd week is still considered full term. Doctors estimate that a pregnancy could come to term 2 weeks before or 2weeks after the official due date. Any time before or after that is considered dangerous for both the mother and child. If the baby comes before the 38th week, he/she is considered premature and could end up in an incubator.
A baby born before the 38th week could have underdeveloped organs or some complications and therefore has to be kept under observation for a period of time. A baby born after the 40th week could mean that the pregnancy date was calculated wrongly but could also mean that the woman is suffering from a number of complications. In most after term babies, surgery is performed.
