30WEEKS & baby is overweight

Had my monthly check up earlier and si baby 1.9kg at 30weeks sobra daw siya ng 200g. 😣 pinapa balik ako after 2wks to monitor ang pag laki niya. Huhu natatakot ako. Meron ba dito same case? Need ko mag diet per my OB at pinapa consult niya ako sa endocrinologist. 😭😭 any advise thank u
