worried about my baby ...

I'm so worried that my little one will be so little when he's born. The last time I went to the doctor she hand measured me baby at weighing "about" 5 lbs and I was 36 weeks. She said it as if nothing was wrong but looking at every <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> I have they say he should be at least 6 - 6.5 lbs. I am now 37 weeks and she said he could come anytime . How much did your baby weigh at 36 weeks ?
