Ay sis, sa second trimester usually mas okay na kayo compared sa first three months, less nausea, more energy na! Most of my mum friends said ang common symptoms nila were mild back pain, occasional dizziness, skin changes (some got acne, iba glowing), at mas malakas ang appetite. Pero honestly every pregnancy is different, kaya best talaga magcheck-in with your OB to confirm everything's on track at normal para sa inyo specifically, lalo na kung may unusual symptoms kayo na worried kayo about.
