Ay, it's possible talaga! A few of us sa mama group namin experienced delayed morning sickness, one friend didn't feel anything sa first trimester pero boom, 2nd trimester hit her hard with the nausea. It can happen kasi every pregnancy is different, and hormones do their own thing. Pero kung nag-start na siya ngayon, best to check with your OB para ma-rule out kung may ibang cause at ma-manage properly ang symptoms. Hoping you feel better soon!
