High Pressure

Hi I'm 23+ 1 day pregnant and had a checkup today and they went over the results of my 20+ 1 ultrasound. Everything looked great development wise, baby's heartbeat was normal, etc. However, they said that the pressure/ blood flow in the umbilical cord was slightly higher than normal. The doctor didn't seem too concerned because she said it was mild at this point and they are keeping me on baby aspirin and I have to go get another ultrasound in 2-3 weeks. I haven't been able to find much on the internet so I was just seeing if anyone else has gone through this and what your process and outcomes were. Thanks!
