Baby's Changes Overview

  • Lung Maturity: The production of surfactant in the lungs is crucial for their first breaths outside the womb.

  • Auditory Connection: Your baby may recognize voices, fostering early communication and bonding.

  • Organ Function: Key organs like the kidneys, liver, and intestines are fully operational, supporting essential bodily functions.
As you progress through this phase, your baby is moving frequently, perfecting those kicks and turns, with the head gradually moving downwards in preparation for birth.

I had my obgyn tell me to continue baby aspirin until the end of that preeclampsia is what happens generally towards the end more. So staying on it is a better option than stopping it.

That’s what I thought. But I’ll be considered full term at 37 weeks. So honestly she can come at 37 weeks. I’m totally okay with it.

My last sonogram was at 28 weeks ish and she was 2.5 something pounds. I have another one coming up on the 25th and I'll be almost 33 weeks so we'll see lol. The weight ranges from baby to baby, I'm expecting my little to be close to 4 pounds give or take. Even if your little is a little on the low side, as long as they're gaining weight you shouldn't worry too much ❤️
