    This is the moment your body has been preparing for during the past first two weeks of pregnancy. This is the week you ovulated, when egg met sperm, and conceived if you have perfectly timed sexual intercourse during your ovulation period. You may now have a single-cell fertilized egg or zygote traveling through your fallopian tube to implant itself in the thickened lining of your uterus. Pregnancy symptoms on Week 3 are unlikely to appear because you're still waiting to see if you're going to miss your upcoming period or not. It's also too early to take a pregnancy test to check if you indeed have a bun in the oven.

    Pregnancy signs Week 3

    You may not feel any changes yet, but your body is experiencing them. As soon as you conceive, your body goes into full-on pregnancy mode.

    Once the fertilized egg had implanted itself in your uterus, your body will develop a placenta, and your body will start producing hCG (human chorionic gonadotropin). Your body's hCG levels are increasing rapidly, but it may still be too low to be detected by even by the most sensitive pregnancy tests kits.

    Aside from the hCG hormone, your body will also start producing pregnancy hormones progesterone and some estrogen. According to What To Expect When You're Expecting, these hormones will help your body nourish and support the future fetus until the placenta is fully formed and functional.

    Pregnancy symptoms on Week 3

    As mentioned, it is still too early to experience many of the typical pregnancy symptoms. Some women may already experience some first signs of pregnancy, but as you will see below, they could also be signs that you're about to get your period.

    Spotting and mild cramping

    If your period is not really due yet, but you have some light spotting for one to two days, this could be a sign of implantation bleeding. It's usually brown or pink in color and often accompanied by feeling a slight abdominal pressure or cramping.

    Not all women experience implantation bleeding. Obstetrician-gynecologist Dr. Ma. Lourdes Poblete-Chan warns that significant bleeding, sharp dysmenorrhea-like pains, and cramping could be a sign of implantation or placenta problems.

    A heightened sense of smell

    The surge of the estrogen in your body can cause you to be highly sensitive to certain odors, mostly in food. Often, though, it helps preggos steer clear of harmful tobacco smoke.

    A metallic taste in the mouth

    You are sure you didn't just chew on a coin, but you swear you can taste metal in your mouth. Again, blame this on the hormones, but you may not even have this if you're often chugging on citrus juices.

    Breast tenderness

    Having sore breasts can also be a sign that you're about to get your period, so this early pregnancy sign is not a guarantee. You may notice, though that your areola is starting to a bit larger and darker.

    Nausea

    Some preggos already experience this even without knowing that they're already pregnant. You can blame your rising hCG hormones for feeling queasy this early on in the pregnancy.;

    Your baby's development on Week 3

    If you do an ultrasound on the third week of your pregnancy, you will still not see a thing, but there are certainly a lot of action going on in your womb.

    As soon as the sperm fertilized an egg, the resulting single-celled zygote will quickly divide and multiply exponentially into more cells in just a matter of hours. After about four days, the ball of cells that was once a zygote, now called blastocyst, is still too tiny, microscopic even, to be seen in the scan. As your pregnancy progresses, these cells will form the embryo, and some will form the placenta.

    What's amazing to note at this time is your baby's inherited characteristics are already set in stone at the moment of conception. A zygote has already formed a complete set of 46 chromosomes, half from you and half from your partner. These chromosomes determine your baby's sex, eye and hair color, skin and body type, and even your unborn baby's cognitive potential and his personality.

    Your to-do list on Week 3 of pregnancy

    You may want to go see your doctor for a wellness/pre-conception checkup if you still haven't done so. This is also an excellent time to relax with a book, perhaps reading up on the early stages of pregnancy.

    Keep taking your folic acid and prenatal vitamins. Make sure you stock up on the essentials nutrients to support your pregnancy. Continue to eat a balanced diet, but boost your protein and calcium intake to help the rapidly growing soon-to-be embryo in your womb.

    If you have a short cycle or a 28-week cycle, and you missed the supposed first day of your period, you can take a pregnancy test at the end of your third week, if you like. You may get a faint second line! Still, if you can wait to do that until a few days into your missed your period to get more accurate results.
