Ay oo, tama ka, superfetation yun ang tawag, pero napakababa ng chances talaga, lalo na kung regular na ang periods mo during pregnancy na walang ovulation! A few of us moms were curious about this din after reading random forums, pero honestly super rare na mangyari especially if you're breastfeeding or the hormones are stable na from the first pregnancy. Kahit theoretically possible, the body's natural mechanisms usually prevent it, kaya walang need mag-worry if you're already pregnant na!
