Pregnancy Facts - Week 7

What's happening in week 7 of pregnancy

Damn you first trimester pregnancy symptoms!


Nausea-relief candy

Amazon For some women, morning sickness can have you visiting the washroom more often than a teenage boy with unfettered access to a smartphone. Many women swear by nausea-relief lozenges, like Preggie Pop Drops or ginger candy, which can help control morning sickness and settle upset stomachs. It's like magic candy.

If your bladder is the thing causing you frequent trips to the washroom, unfortunately there's no candy that can help with that.


The reason for your increased need to visit the washroom has everything to do with space inside your torso. Your organs are shifting around as the womb gets bigger to give your baby ample space to grow. This means your other organs are squishing up against each other, which results in added pressure to them all, including your bladder.

With all that energy spent on providing for the baby, it's no wonder you're extra tired these days.


Your baby's development in week 7 of pregnancy

  • This week, your baby begins to develop brain cells on top of the foundation of neural tubes that started growing in week 5.
  • The umbilical cord and placenta have formed and attached itself to you. Instead of your baby feeding off the wall of your uterus, the placenta is now providing the blood, nutrients and antibodies that your baby needs through the umbilical cord.
  • Your baby now has a little heart that is beating at 140 beats per minute, delivering blood through newly formed blood vessels.
  • The liver and kidneys are now open for business to detoxify blood and filter spent blood, respectively.
  • The flipper-like appendages of your baby now have webbing between the fingers and toes.
