What you need to know about normal 7 week ultrasound, pregnancy ultrasounds.

Hi there, welcome back to another post, Today the topic will be “Normal 7 week ultrasound” if you reach this point you are probably full of questions and fears, after all the first trimester is crucial, but relax you are doing fine, at 7 weeks your baby is growing and changing a lot, stay with me for a little longer and you will find out why!!!


At 7 weeks your baby is about the size of a Blueberry, in measurements, your baby should be about 0.50 inches long, from week 6 to week 7 your baby has probably double the size if the growth was appropriate !!!

Also, do you know that at 7 weeks in your baby’s brain 100 new cells are developed per minute, and not only your baby’s brain is becoming more complex but the heart is becoming complex too. Your baby is developing the kidneys, arm and legs are now forming as well.

7 weeks pregnant symptoms.

  • Nausea: Morning sickness may be going strong at 7 weeks of pregnancy, if you expecting twins, morning sickness is probably worse due to highest levels of hormones, but don’t worry it should get better after the first trimester, some moms-to-be finds relieve taking Ginger natural tea or vitamin B-6.

  • Food cravings and/or aversions: You probably find yourself craving for weird foods, same as not wanting to eat foods that you thought was delicious before, don’t worry all of this is normal. It is ok to give in to your cravings and indulge once in a while, but try not to go crazy, and make healthy food choices instead when is possible.

  • Mood swings: Not only your hormones are all over the place but you can be feeling emotional and overwhelmed by the idea that you are pregnant, so don’t worry it will get better soon.

  • Frequent urination: Your uterus at this point even though you don’t look pregnant has doubled in size, also know that your uterus anteriorly is pressing against your Urinary bladder.

  • Acne: Breakouts in multiples areas of your body are due to hormonal changes, you can use certain products to ease the symptoms but please before you use anything check with your doctor if they are safe to use while you are pregnant.

  • Cramping or spotting: Sporadic mild cramping with pink or brown spotting can be normal, after all, your uterus is growing rapidly and your cervix must be sensitive too, however, an Ultrasound is always recommended to Rule out miscarriages.

And finally the assessment of the pregnancy is done, measurements are obtained on the embryo to correlate Last menstrual period dates if you don’t know your Last menstrual period don’t worry these measurements are accurate enough to generate an Estimated Due Date. This measurement is called Crown-Rump length ( CRL).

  1. Amazing! I was in the field of ultrasound in urology, don’t ask, and saw over 5, 000 patients in six years. Left that and went into urology sales with Cook. Now, 23 years later, I’m still with Cook but in the Biotech division. God bless you for doing what you do!
