This is the fourth week and confirmation of your pregnancy has been done.  This week the embryo has found its way to the uterus and is looking for a suitable place to nestle in for the next 36-38 weeks or so. The embryo is now called a blastocyst.   This is also the time when most women are expecting their period.  Some of you may experience a slight bleed in the fourth week.  Do not worry.  Slight bleeding or spotting is implantation bleed and not a regular period.   The uterine wall is so engorged with blood at this stage that any disruption can cause a light bleed. You just missed your period and if the test came back positive “You Are Pregnant”

Calculating Estimated Due Date or EDD is quite a simple process.  However, confusion occurs when talking about how many months one is pregnant and how many weeks long is the pregnancy.  The estimates are based on the following:

  • Last Menstrual period is required to be known
  • Add 40 weeks to the end of the last menstrual period and that is the EDD
  • Alternatively, you can add 280 days to the end of the LMP
  • A normal pregnancy is approximately 266 days from conception to birth
  • It normally takes two weeks for your period, ovulation and fertilization. Hence conception occurs approximately 14 to 16 days after the first day of your last menstrual period (LMP)
  • Pregnancy is often broken down into weeks and 40 weeks is considered to be full-term pregnancy.
  • Any baby delivered in less than 37 weeks is considered to be premature.
  • Fertilization is counted to have occurred around the 14th day of the 28-day cycle of menstruation. This is so due to ovulation occurring about 14 days before the start of your period.
  • The EDD calculated is only a guide. Average pregnancy can last anywhere from 38 to 42 weeks.

Another terminology used to specify the stage of pregnancy is trimester.  A simple way to determine which trimester you are in is as given below:

Trimester 1

  • Week one to thirteen
  • First month to the third month

Trimester 2

  • Week fourteen to week twenty-six
  • Fourth month to the sixth month

Trimester 3

  • Week twenty-seven to week forty
  • Seventh month to ninth month
