DAY 1 • OF WEEK 5
Implantation is where it all begins. It is when the zygote embeds itself in the uterus. This implantation can have symptoms, such as light pink spotting, cramps, and some twinges in the lower abdomen. These signs may appear between 7 and 15 days after the fertile period… Continue Reading
DAY 2 • OF WEEK 5
Having an ultrasound at 5 weeks is very commonly alarming due to a “fetal absence.” This happens because the embryo is very small and cannot yet be visualized on ultrasound. In some cases, you can see a small spot, which is the gestational sac… Continue Reading
DAY 3 • OF WEEK 5
Many people associate belly size with pregnancy symptoms. However, abdominal bloating is not always a sign of pregnancy. Belly bloating happens due to increased progesterone and may even be seen after ovulation. Only in combination with missed periods does it suggest pregnancy… Continue Reading
DAY 4 • OF WEEK 5
There are two options for pregnancy tests: qualitative and quantitative. The qualitative test detects the amount of HCG in the blood, indicating positive or negative. The quantitative test, in turn, uses the level of HCG to assess the evolution of pregnancy and how many weeks it is… Continue Reading
DAY 5 • OF WEEK 5
With bleeding that sometimes confuses women, implantation may occur when menstruation is expected or even with a few days’ delay. The difference is in the amount: implantation bleeding is light and does not come with heavy, bright red blood like menstruation… Continue Reading
DAY 6 • OF WEEK 5
The way obstetricians calculate pregnancy can often confuse women. The calculator helps make it easier to count weeks and see which phase you are in. It can also indicate the approximate due date of your baby… Continue Reading
DAY 7 • OF WEEK 5
Once you finally see a positive, after the initial shock it’s essential to see an obstetrician to monitor the evolution of pregnancy with prenatal care. Having some tests to check the woman’s health is also indispensable. And of course, an ultrasound to watch the embryo’s development.
key information box:
- At 5 weeks of pregnancy, the embryo’s heart is already beating! Yes, and if you’re lucky on the ultrasound, you can see the rapid rhythm of this tiny heart that’s almost invisible.
- At this stage, the head is the fastest-developing body part. The brain and nervous system are going full steam. For this reason, mothers should take folic acid from the beginning.
- At 5 weeks of pregnancy, ultrasound is not recommended, as you may not see anything and end up leaving the office frustrated and worried.
- At this stage, a woman should have already missed her period. But if not, hormones will give her a clue. Mood swings can be a real roller coaster!

More information about 5 Weeks Pregnant
At 5 weeks pregnant, the embryo already has a beating heart! Yes, and if you’re lucky with the ultrasound, you can see the fast rhythm of the heart, so tiny it’s almost invisible. Its size is comparable to the tip of a sewing needle. Its head and heart are so small that an ultrasound at this stage would make it impossible to detect.
At this stage, the head is the part of the body that develops the most. The brain and nervous system are forming at full speed. That’s why it’s so important for mothers to be taking folic acid. It helps prevent embryo malformations1. The entire structure of this tiny body is practically formed by 5 weeks of pregnancy. The yolk sac will become the placenta, which provides support through small blood vessels, delivering all the oxygen and nutrients the baby needs to grow properly.
Now at 5 weeks, the embryo is no more than 2mm! Imagine a tiny grain of rice, still undefined in shape. It really looks a lot like a tadpole, but the cutest one possible. Soon it will take on human features and be easier to see on ultrasound.
Ultrasound at 5 weeks
Speaking of ultrasound, some women have them at this stage of pregnancy. It’s common not to see the baby and only see the gestational sac, as well as the yolk sac at 5 weeks. If this happens, don’t worry—it’s perfectly normal!
The heart may start to beat during this 5th week, though not yet with a constant rhythm. However, it’s expected that the tiny heart will normalize its beat soon2. The beats begin with an involuntary contraction of one of the heart’s ventricles, which stimulates the others around it. Within seconds, the heart starts beating, and a new life inside you becomes even stronger!
How mom is feeling
At this stage, most women have already missed a period. But if not, the hormones will give you a sign. Mood swings can be a real rollercoaster! Sometimes sad, sometimes happy, sometimes irritable, sometimes extremely hungry or feeling completely nauseated. At this stage symptoms start appearing3, but some women don’t feel a thing! The fetal development of the embryo will bring even more symptoms. Right now, it is stimulating the corpus luteum, which supports hormone production in the beginning of pregnancy.
At this stage, it’s ideal to find a trustworthy doctor if you don’t already have one. You need to start prenatal care as soon as possible. If you haven’t had blood tests yet, your doctor will order them. Don’t be afraid—there will be many! You might be frustrated by how long you’ll have to wait to get an ultrasound, but remember—the longer you wait, the better. It will give time for fetal development to take place and you’ll get a more accurate view of your little miracle!
From week 7 on, it’s the best time to have a more reliable ultrasound. I myself had an ultrasound at week 7, and the doctor said I was only 6 weeks along. That means if I did it earlier, I wouldn’t have seen anything! And this happens more often than you think. So, try to keep your anxiety and your heart in check.
External factors
The world is going to feel much more colorful, and your skin might look different (either less or more oily or dry), and your hair will look shinier! You’re beaming and the difference that motherhood is bringing you is clear to see.
You may suddenly not like your favorite shampoo or perfume anymore. Remember that any medication you’re taking should be stopped, but only under medical advice. Talk to your gynecologist to change any medication you take regularly or stop those that could potentially harm fetal development.
Readers’ Questions:
How big is the fetus at 5 weeks?
The size of a fetus or embryo at 5 weeks is still so tiny that it can be compared to a minuscule grain of rice. Its shape is not yet anything like a real baby.
Is there already a baby bump at 5 weeks pregnant?
No. Even though some women say they already feel more bloated, that’s impossible. The embryo is so tiny that it can’t yet expand your uterine size.
Is it possible to feel the baby move at 5 weeks?
No, at 5 weeks, even the heartbeat cannot be detected during an ultrasound. It’s much too early to feel movements or kicks.
