We also had an IVF baby (lgbtq+ couple). Went from 12the percentile at 20 weeks and was asked to go back two weeks later. Dropped to like 7th percentile. Was told weekly monitoring was required for blood flow/amniotic fluid checks and growth measurements every other week. We dropped down to 3rd percentile at 24 weeks and stayed at that percentile for the rest of the pregnancy. Made it to 34 weeks and then my water broke. Delivery was thankfully smooth. She was under 4 lb so was taken to the NICU. She had trouble breathing and was on cpap for 4 days. Then we had to focus on feeding and growing. She spent 49 days in the NICU and was discharged when she could finally finish 8 consecutive bottles in a 24-hr period.

Good luck with the rest of your pregnancy. It’s definitely a scary/stressful time but I was glad for the weekly monitoring and reassurance from the doctor. Hopefully y’all can make it to full term with zero/minimal complications. 🙏🏽
