35th percentile

So after being told my baby was measuring 4 weeks behind at 32 weeks, I was sent for a growth determination ultrasound. I had my follow up apt today (I'm 34w 4d) and the doctor said baby is measuring in at the 35th precentile...50 being average and 15 & under being a concern. She told me it's not a huge concern at this point, but in 4 weeks I have to go for another growth ultrasound, if baby's growth isn't coming in in the 50th precentiall or above, that I will be induced. The doctor said that my Baby's parts are all measuring fine, she is just small...but I'm still worried. Has anybody gone through or going through something similar?
