1 Week Pregnant: Your Period!

At this stage you are not physically pregnant and you are on your period. Not fun.

Pregnancy calendar begins before conception. Medical professional count pregnancy weeks from the first day of your last menstrual cycle. Doctors use LMC to estimate the likely due date until an ultrasound is performed for more accuracy.

Pregnancy lasts about 40 weeks or 280 days from Last Menstrual Period. The 40 weeks happens to include the non-prego 1st 2 weeks (Last Menstrual cycle to conception) to until you are actually pregnant.

Due dates are estimated from both approximate conception dates and first day of last menstrual period. So 266 days days after conception date would be your estimated due date and 280 days after your first day of period would also be your estimated due date.

2 Week Pregnant: Ovulation

In this week, Ovulation may be just days away. You can become pregnant at approximately 14 days after the first day of period. If you have sex towards the end of this week, the sperm and egg may likely meet and conception will take place. If this happens, your uterus is about to have a party!

3 Weeks Pregnant: Conception!

In this week, a lot of activity is taking place in your belly. You may not be able to tell though. If the sperm and egg have met, they will join in the fallopian tube to form a zygote(a single cell) in this process called fertilization. A chromosome from both mother and father is joined to form a zygote and sets the first building cells for your baby’s genetic makeup material. The zygote then travels down the fallopian tube, towards the uterus and starts dividing into larger groups of cells.

Symptoms at Weeks 1,2, or 3?

You will not suspect you are pregnant duration of weeks one, two or three of your pregnancy. Symptoms are little to none. One symptom that women may experience is implantation bleeding once a blastocyst(no longer a zygote), attaches to uterine lining.
