First-Week Pregnancy Signs

First-week pregnancy signs or early symptoms of pregnancy can start as soon as one week after conception, but most people don’t experience symptoms until a few weeks after a missed period. Symptoms vary from person to person, and some may not experience any symptoms.

First-Week Pregnancy Signs:

  • Fatigue: Can start as early as one week after conception.
  • Spotting: Light bleeding or spotting can be an early sign of pregnancy. This is called implantation bleeding and happens when the fertilized egg attaches to the uterine lining.
  • Breast tenderness: Breasts may feel tender.
  • Mood swings: Hormonal changes can cause mood swings similar to those that happen before a period.
  • Smell sensitivity: Hormonal changes may cause increased sensitivity to certain smells.
  • Cramping: Mild cramping can occur as the uterus stretches.
  • Bloating: Bloating is a common early symptom.


Other early signs of pregnancy can include:

  • Morning sickness
  • Increased vaginal discharge
  • Frequent urination
  • Headaches
  • Backaches
  • Difficulty having a bowel movement

Dating Your Pregnancy

Why do doctors add 2 weeks to the day of conception to date the pregnancy?


Most doctors count the duration of pregnancy starting from the first day of the last menstrual period (LMP). This is because it is hard to know exactly when a woman ovulates and conception occurs. It is easier to know the first day of a woman’s last menstrual period. On an average 28- day menstrual cycle, her period starts two weeks prior to ovulation and conception. So, if you think you became pregnant about two weeks ago, you are likely to be around four weeks pregnant according to medical professionals.


If you have concerns about when you conceived, the most accurate way to date the pregnancy would be through an ultrasound. We can provide one at no cost to you.
