One week pregnant is actually not pregnant at all. Most OBs count pregnancy starting from the first day of your last period. That’s because ovulation and conception are really tough to pinpoint. Rathar the physical signs of menstruation are much easier to recognize. You won’t actually conceive your baby until week two or three, depending on the length of your cycle.
The average length of full term pregnancy in women is counted as 40 weeks (280 days). But the period an unborn baby spends in its mother’s womb is 38 weeks. This difference is because conception generally occurs after two weeks from the first day of the woman’s last menstrual period (LMP).
When you are actually thinking of that lovely baby growing inside you for the first time, you are already two weeks pregnant.
During the time that you have your menstrual period, new eggs start to develop in your ovaries.
Conception only happens about two weeks after your period starts.
Nevertheless, once you have fallen pregnant, your doctor will calculate your expected due date from the first day of your last normal menstrual cycle.
Your due date is calculated on the basis that you will be pregnant for 40 weeks.
Pregnancy or the gestation period in women is divided into three trimesters: First trimester – From conception week to week 13, Second Trimester – from week 14 to week 27, Third trimester – from week 24 to week 40 and Forward. Find out what is happening with you and the baby in these stages, week by week.
