Hindi ko alam kung mababa talaga based sa photo lang kasi ang bawat mama at bawat baby ay iba, pero definitely check with your OB para sure lang, they'll measure properly and make sure baby is growing okay! A few of my mum friends were worried din about the same thing during their third trimester, pero pag sinuri ng doctor, all good naman. How are you feeling otherwise, and how's your weight gain going?
