Congratulations! By week three of your pregnancy, ovulation and implantation typically occur. Here’s what you should know about your body and your developing baby during this crucial time.
Understanding Pregnancy Calculation
Pregnancy can be a bit confusing to calculate. Most women are unsure when conception happens, as pinpointing the exact moment of ovulation is challenging. Therefore, pregnancy is usually calculated from the first day of your last menstrual period. Given this method, a typical pregnancy lasts about 40 weeks.

Physical Changes You Might Experience
During this week, many women won’t notice significant changes. However, some may experience mild cramps and increased vaginal discharge around ovulation. At this stage, your ovaries release a mature egg, which then travels through the fallopian tubes toward the uterus. Meanwhile, sperm journey through the uterus to fertilize the egg, with only one sperm successfully merging with it. Both sperm and egg contribute 23 chromosomes each, forming a zygote with a total of 46 chromosomes. Remarkably, at conception, your baby’s sex, eye color, hair color, and many other traits have already been determined.
The zygote continues its journey to the uterus, where it attaches itself to the uterine wall. For more insights on ovulation, see our FAQ on understanding ovulation.
Development of Your Baby
This week, the blastocyst is rapidly growing and multiplying. Part of this blastocyst will eventually form the placenta, which produces hCG (human chorionic gonadotropin), the hormone detected in pregnancy tests. Amniotic fluid is also beginning to accumulate around the cells, providing protection and cushioning for your baby during pregnancy. Significant fetal development begins this week, including the formation of the brain, spinal cord, heart, and gastrointestinal tract.
How Big is Your Baby?
At this point, the embryo is extremely tiny, resembling more of a cluster of cells than a baby. It’s about the size of a pinhead, measuring roughly 0.0019 inches (0.048 mm) long. You would not be able to see it without advanced imaging technology.
Planning for This Week
Exercise plays an essential role during pregnancy. It’s advisable to consult your healthcare provider before starting or continuing any exercise routine. Generally, if you’re already active, you should be able to maintain your routine. For some excellent recommendations on safe exercises during pregnancy, take a look at our curated list.
It’s crucial to remember that your baby is affected by everything you do—both good and bad. Avoid alcohol, illegal drugs, certain medications, caffeine, and tobacco. Nutrition is particularly important during this early stage; essential nutrients like folic acid and other vitamins are crucial for fetal growth. Maintaining a balanced diet with adequate protein and calcium is beneficial for both you and your baby. If you have questions about dietary recommendations, reach out to your doctor.
Tips for a Healthy Pregnancy
Your body is undergoing significant changes, which can sometimes feel overwhelming. Ensure you get enough rest and maintain proper nutrition. Take time to relax and enjoy the experience of being pregnant.
Advice for Partners
Both you and your partner may begin to feel anxious, even if the pregnancy was planned. Open communication is key; discuss any concerns and ask questions to ensure both of you feel involved in the pregnancy journey. Consider planning small, thoughtful ways to support each other over the next 37 weeks.
