Baby measuring small at 36 weeks

Hi. I’m going into my 36 weeks soon and I went for my usual routine scan yesterday. (35+5). Gynae says that baby is measuring small at about 2.2kg :( my previous scan at 31weeks, baby was around 1.5kg. So she said baby’s growth is slow and should be more than 2.5kg by now. she also told me that it’s not because I’m not eating enough because blood test shows that it’s my placenta “ageing” earlier than expected. She suggested inducing my baby at 38 weeks if baby’s growth is stagnant due to my incompetent placenta. Any advices or anyone who went through the same thing as me?
