1 Week Pregnant is it Early to Tell?


At 1 week pregnant, your baby is barely seen because he is too little at this point to be able to be distinguished. In fact, you may not even be aware that you are pregnant! But though it may be unnoticed, some women may start to notice some changes in one’s body when they are 1 week pregnant.

Your Body at 1 Week Pregnant

In the first week, symptoms of pregnancy may not immediately show. If you are curious though, one of the first signs that you will likely feel are fatigue, mood swings, becoming less interested, and frequent urination. Ironically, these signs, when a woman is 1 week pregnant, are often assumed as PMS symptoms.

Typically, one’s menstrual cycle can go for 28 days, even though at times it can only go for 24 days to 35. The conception date will start two weeks following your menstrual period’s last day. You’ll also begin calculating your pregnancy due date by adding seven days to the first day of your last period, minus three months and adding a year.Your body is also readying for your ovulation. At this point, your uterus is preparing the arrival of fertilized egg. But, you may not notice if the egg has fitted with the sperm until the next month.

An egg goes out your ovary to travel into your fallopian tubes. When the egg reaches the fallopian tube, a sperm will meet the egg and fertilization occurs. Starting from there, the successful fertilized egg goes again to your fallopian tube going to your uterus. At this point, an implantation will happen. However, there are people who may think that a woman is not actually pregnant on the first week because the fertilization of the egg occurs the following week, and this is why most pregnancies are not detected at first week.

There are no known changes that may occur to you physically. However, many changes are going on inside your body, such as problem in digesting food like constipation and gas, tender breasts, mood swings, fatigues, hormonal changes as well as morning sickness. However, some women don’t experience these symptoms until they are on their second week of pregnancy.

Baby’s Development

On the first week of your pregnancy, your baby isn’t going through any major baby development. It is still a small single celled egg called ovum. You can’t see it with your naked eyes and you will not be aware that developments can even happen to it.

Your soon-to-be daughter or son is still an egg leaving your ovary and making its way to your fallopian tube, as mentioned earlier. At this point, you’re not yet pregnant, since your conception will happen about two week following the end of your menstrual period. However, this development that is happening on your first week is still included in the pregnancy calendar’s calculation.

After the fertilization of the egg, the cells will divide within seven to ten days. Your baby will be called blastocyte. The blastocyte will begin to break in two. The external region will be the placenta while the internal part will grow into an embryo, which will occur during the second week of pregnancy.

When two or more eggs have been released and undergo fertilization, several zygotes will be created. The zygotes have 46 chromosomes which come in equal number from parents. The chromosomes contain genetic material that define the baby’s sex, features, hair color, height, skin color, and eye color.

Prenatal Care Needed

Doctor’s appointment

Take a regular visit to your obstetrician. Schedule your appointments for preconception. You will learn more about the dangers on genetic, environmental and lifestyle that will risk your health and your baby.

If you’re trying to conceive and you have the feeling that it will occur soon, take prenatal vitamins at this point. Over the next months, you will notice many changes in your body. Talk to your doctor regarding your prenatal multivitamins. Folic acid is needed every day and it must be at least 400 micrograms. Taking this vitamin will prevent birth defects such as problems in the brain, heart, and spinal cord. It should be taken in the early weeks of your pregnancy or before you conceive. Make sure all supplements have calcium, iron, and Vitamin B12.

When it comes to medication, make sure that you consult your health care provider and ask the effects of the medication and the dosage. Whether it is a prescription medicine or herbal, you must still consult your doctor. Taking medicines without knowing the effects could affect your pregnancy, especially the health of you baby.

Personal check

If you have been also checking your basal body temperature, it is likely that you’ll notice that your temperature is still elevated beyond day 16 ofpost ovulation. Monitor it every morning and before you sleep.

Now that you’re to become pregnant, make changes of your physical habits as well as on the food you eat. You may also want to reduce or completely stop your coffee intake. According to the National Infertility Association, drinking too much coffee or caffeine in your system, with more than 8 ounce cups or 2 weak-brew coffees every day, can get in the way of fertility for some women.

If you are a smoker, quitting it earlier is best. But if you’re trying to get pregnant, get rid of your smoking habits immediately. Smoking affects your fertility as well as brings health risk to your unborn. If you can’t stop it, seek advice from your health care provider.

Final advise

Pregnancy is a blessing to women. However, some are not successful on their first week, making it stressful for them. Trying to get pregnant may not be easy, but try to cheer yourself up. Frustrations and stress will only make you unhealthy thus, reducing your chances of carrying a bump. Make sure you have enough sleep and practice good eating habits. Do something interesting like shopping and watching movies with your partner and reconnect each other. Or try this, don’t use electric blankets, instead keep each other warm. According to a research, prolonged and excessive heat coming from electric blankets or heating pads affects those temperamental testes. The said heat will make the production of sperm slow.

So that’s it about some information that can guide you if you think you are 1 week pregnant.
