Pregnancy: Week 1

1 Week Pregnant

1 Week Pregnant

When you're 1 week pregnant, it usually goes without you realizing you’re pregnant. At this point, your period may be already late, but if this is commonplace to you, then you probably assume this is completely normal.

Pregnancy Symptoms at 1 Week

What are the signs of pregnancy at first week? During week one, there aren’t any immediate symptoms that may indicate the presence of pregnancy. Most commonly, women experience:

Given their similarity to PMS, it’s very likely that, if you’ve already experienced these symptoms, you’ve already thought that it’s just the onset of your period. Although no noticeable physical changes take place in your body, there are a few internal symptoms that start happening, these include:

Though the latter is more common toward the end of the first trimester. The symptoms vary strictly from woman to woman, and many don’t even experience them until week two of pregnancy. Since your egg has only been fertilized at this point, and implantation hasn’t occurred yet, the first week of pregnancy is what doctors call “get out of jail week.” In other words, what you eat or drink won’t have any impact on the course of the pregnancy at this point, so it’s okay if you have one glass of wine with dinner, or if you eat hamburgers on a daily basis.

Your Baby’s Development

There is no major development of the baby during week one of pregnancy, other than the fertilized egg leaving the ovary and traveling to the fallopian tubes. Many people speculate that a woman isn’t really pregnant until about two weeks after your period ends, since that’s when conception itself happens. The reason why this week is included in your pregnancy calendar is to help your doctor calculate the first day of your last menstrual cycle, and your estimated delivery date based on the 9-month (or 40-week in medical terms) cycle.

Pregnancy week 1

What is conception? When the egg meets a sperm cell in the fallopian tube, and fertilization occurs, it starts to divide over the next 7-10 days. At this point, the embryo is called a “blastocyte,” and it has two parts — an external part that will be the placenta, and an internal part that will develop into a fetus during the second week of pregnancy. The baby’s gender, hair color, features, skin color, height, and eye color is determined right when fertilization occurs. The gender is determined by two chromosomes, X and Y. Naturally, a female is XX, while a male is XY. When a baby is made, the mother contributes to his/her gender with an X, while the father can contribute with either an X or Y. If the sperm cell that fertilizes the egg carries another X, then the baby will be a girl; if it carries a Y instead, then the baby will be a boy.

How to Say If You’re Pregnant?

Probably the first symptom of pregnancy during week one is increased basal body temperature. As you probably know, when you ovulate, your BBT rises by one degree. If the egg gets fertilized by a sperm cell, the BBT remains elevated beyond day 16 of you’re the luteal phase (based on a 28-day menstrual cycle). An increase in your normal vaginal discharge is also normal, so don’t worry if there’s more cervical mucus than usually.

Pregnancy Tips

  • Contact an obstetrician and get medical advice on whether it’s fine to continue taking medication (if any).
  • If you haven’t already, then week one of pregnancy is the perfect time to start taking a folic acid supplement.
