Baby small


Hi mommies I’m due on 24 January 2020, and my doctor is currently out of the country he will be back next month, so I went to just a random doctor but she is a gynecologist, I’m currently 31 weeks and she said baby is doing perfectly well no complaints but the only problem is that my baby is weighting sooo small she is just 1,5kg and she is like I’m measuring two weeks behind which is stressing me a lot.. I will be operated in January second week I think and I’m praying my baby will measure at least 2,5 kg normal birth weight.. any mommies experience something like this?
