Pregnancy Week 1

Fetal development in pregnancy week 1

It’s been a momentous past couple of days—even if you don’t know it yet. At some point roughly 1.5 – 3.5 million sperm took aim at your fallopian tubes and one superior little seed hit the target spot on. The now fertilized egg is still inside your fallopian tube and is already merging with the sperm to become a zygote. Cell multiplication is occuring at an astonishingly rapid rate. Your little zygote will spend the next 7-10 days dividing and multiplying as they slowly descend into the uterus, where it will nestle into the already cozy blood-rich uterine wall. The implantation process may result in a little spotting for some, caused by the sloughing off of uterine wall at the implantation site. This is perfectly natural and not a cause for concern. When your little zygote is finally implanted, it is a blastocyst measuring about 0.1 – 0.2 mm. This will be your baby’s spatially-challenged home for the next 38-40 weeks.

Maternal Changes

Your period has just started and you may be thinking about conception. For women with a 28 day cycle, ovulation occurs around 14 days after the start of your menstrual cycle. Now is a good time to begin healthy habits (if you haven’t yet!). Start your pregnancy diet with plenty of fresh fruits and vegetables; exercise; start taking additional folic acid if you haven’t already; and stop smoking, drinking alcohol, and using over-the-counter medications. Stay away from toxic materials and rest well. Start “thinking pregnant” before you conceive so you can give your baby the best start possible.


Many fathers-to-be also begin watching what they eat and drink. The health of dad does play an important role in baby’s health and development. Now is the ideal time to stop smoking, develop some better eating habits and other healthful goals.

Pregnancy Week 1 Symptoms

  1. You will feel tired easily and this will be more noticeable if you are healthy and active. If you are feeling like fainting then also take it seriously as due to low blood pressure during the early days of pregnancy you may faint also.
  2. Nausea is also common sign of pregnancy. Mainly you will feel nauseous during the morning but many women can also feel nauseous all throughout the day too. There will be vomiting also.
  3. Implantation bleeding is one of the very common early pregnancy symptoms. During the implantation of the fertilized egg in the lines of the uterus, slight bleeding will be caused, which will appear pinkish brown in color.
  4. If you are visiting the washroom more than often, then there are chances you are pregnant. Frequent urination is also common in first week of pregnancy.
  5. Varicose veins will be also visible, mostly in your breasts. Your breasts will feel heavier and sensitive.
  6. Mood swings will occur often. You will feel depressed, and anxious. Sometimes you will feel very happy and sometimes very irritated.

Twin Tips

Early pregnancy ultrasound can usually diagnose multiple gestational sacs, and there by you know early on. However, early ultrasound can also miss an early multiple gestation. Some reports say that the appearance of sacs via ultrasound can be different by up to 4 days. Early ultrasound is also more helpful in determining how many sacs are present and whether or not your babies share the same sac (monoamniotic). Monoamniotic sacs occur only in identical babies and places the pregnancy at a higher risk for problems like cord entanglement.
