At 3 weeks pregnant, conception may have happened, although you may not know it yet. If sperm met the egg after ovulation, the fertilized egg starts dividing into more cells while moving through the fallopian tube toward the uterus.
This early cluster of cells is tiny and cannot be seen or felt. Near the end of week 3 or early in week 4, it may reach the uterus and begin implantation in the uterine lining. Implantation timing varies, which is one reason early pregnancy symptoms and test results can differ so much.
Week 3 follows 2 weeks pregnant, when ovulation and the fertile window are the focus. It belongs to the first trimester. Next, read about 4 weeks pregnant, when a missed period and a positive pregnancy test become more likely.
You probably do not feel pregnant yet. Some people notice mild cramping, breast tenderness, tiredness, bloating or a small amount of spotting around implantation, but these signs are not reliable on their own. They can feel very similar to normal premenstrual symptoms.
A home pregnancy test may still be negative at 3 weeks pregnant because the pregnancy hormone hCG usually rises after implantation. Testing closer to your expected period gives a more reliable result. If you test early and get a negative result, repeat the test a few days later if your period does not arrive.
Light spotting can happen, but heavy bleeding, severe abdominal pain, one-sided pelvic pain, shoulder-tip pain, dizziness or fainting should be assessed promptly by a healthcare professional.
