3 Weeks Pregnant | Pregnancy Week By Week


It’s finally happened – you’re pregnant!

At three weeks pregnant, a super macho sperm has won over one of your eggs and conception has taken place. The odds were in your favor this month for sure!

Even though you’re pregnant, it’s so soon that you probably don’t even know it yet. At this point, the baby is just a ball of cells (smaller than a grain of salt!) looking for the perfect spot in your uterus to call home for the next nine months.



In week three of pregnancy, it’s unlikely you’ve missed your period yet (the one symptom of pregnancy every woman looks forward to), and the pregnancy hormones need time to build up before you’ll notice any other symptoms. Yes, that means more waiting, as if the last two weeks (or longer if you’ve been trying a while) of waiting haven’t been torturous enough, right?

That’s not to say that it’s impossible to begin feeling symptoms at three weeks pregnant, though. It all depends on how quickly your body produces the pregnancy hormone hCG (human chorionic gonadotropin).  

As your body begins producing hCG, you may start experiencing some of these very early pregnancy symptoms at three weeks.

  • Implantation bleeding. You may notice a little bit of brown or pink spotting in your underwear or when you wipe. Implantation bleeding occurs when the egg has been fertilized and the embryo is attaching to the wall of the uterus. Not all women experience implantation bleeding, so don’t be alarmed if you haven’t noticed it.
  • Missed period. It may be too early yet for you to be expecting your period this week, but if it’s due and you miss it, run out and grab a pregnancy test for confirmation that you’re pregnant! And then, of course, jump for joy at not having to deal with pads or tampons for the next nine months! Think of the money you’ll save that you can use for new baby things!
  • Morning sickness. Feeling queasy? That could be a good sign that you’re pregnant. Most women experience some level of nausea during their pregnancies. Okay, let’s just be honest – you’re probably going to throw up. A lot. There’s no rhyme or reason to morning sickness, despite its name, it doesn’t just occur in the morning. If you’re super unlucky, you could end up with all-day morning sickness. It usually subsides after the first trimester, but there are some women who have morning sickness up until the day they give birth.
  • Tender breasts. As the pregnancy hormone increases, your boobs will get tender. You’ll declare them a no-touch zone to your significant other and belly sleeping will be out of the question.
  • Dark nipples. Pay attention to the color of your nipples because if you’re pregnant, they may get darker. Your partner may even notice this change before you do.
  • Positive pregnancy test. You may decide to test this week if you’re experiencing other symptoms, or if you’re just anxious to find out. Keep in mind that at three weeks pregnant, it’s very early and your hCG levels might not be high enough for an at-home pregnancy test to detect, so even if you’re pregnant, you may get a negative result. If you do get a negative result, try testing again in a few days. In some cases, women will have a blood test done to see if they’re pregnant. Blood tests at your doctor’s office can detect smaller amounts of hCG, so it’s possible to get a positive result very early on. Unfortunately, unless you suspect an ectopic pregnancy or have had previous miscarriages, it’s unlikely you will be able to get a blood test done to confirm pregnancy.



At three weeks pregnant, you won’t have a baby bump. Most pregnant women start having visible baby bumps at around 12 weeks pregnant, so you still have awhile to go. For now, be thankful you can wear your regular clothes for a few more months before you have to buy a whole new wardrobe to get you through the rest of your pregnancy. Go ahead and buy at least one pair of maternity pants. One day in a couple months, you’ll wake up and nothing will fit. Just like that. You’ll cry a little bit, but then you’ll slip on those pants with the large elastic belly panel, pull them up to your armpits and be grateful you thought ahead.



You probably won’t have an ultrasound at three weeks because, at this early stage, ultrasounds can’t pick a whole lot up. The baby, who at this point is a cluster of cells too small to be seen with the naked eye, has a bit more growing to do before you’ll be able to see him or her on an ultrasound. When you schedule your first appointment with your ob/gyn, you can ask when they will perform the first ultrasound so then you’ll know when you can see your little bean for the first time!



Now is the time to start preparing for the next nine months, if you haven’t already. Here are a few things you can do to get your pregnancy off to a great start.

  • Take a pregnancy test. Of course, the first thing you’ll want to do when you suspect you’re pregnant, is take a test. Remember, because it’s still very early, you may get a negative result even though you are Just test again in a few days when your hormone levels have had a chance to increase, and you should get a positive.
  • Take prenatal vitamins. You’ll need to start taking prenatal vitamins so your baby can get all the nutrients it needs for healthy development. You can buy prenatal vitamins over the counter or ask your doctor for a prescription.
  • Increase your calcium intake. Pregnancy uses up a lot of calcium, so it’s important that you increase your calcium intake. After pregnancy, a lot of women begin having problems with their teeth. This is because the baby sucks up as much calcium as it can get to help it grow healthy and strong, which means your body doesn’t get enough calcium. To avoid this, take calcium supplements and/or eat calcium-rich foods.
