Congrats on your first pregnancy, sis! Honestly, ito ay best discussed with your OB kasi everyone's pregnancy is different, some doctors ay okay na mag-light exercise from the start, some ay mas gusto nila maghintay first trimester, depende sa condition mo. A few of us moms, nag-start kami ng walking at prenatal exercises around second trimester after getting the go-ahead, pero really talaga, ang safest route is to ask your doctor directly kung anong exercises okay para sa iyo at at what point. Excited ka na mag-exercise, which is great, pero better safe than sorry lalo na first time mom ka pa!
