Just asking

Hello everyone may tanong po sana ako I have I baby that 9 months old and I gave birth on January 2 2022. And breastfeeding po ako sa kanya ever since and then I don't have my menstruation since then. Gumamit ako ng pt ang result is negative KayA nmn po ako gumagamit kasi lumalaki po yung tyan ko. Pwede po ba na buntis ako ulit or that's natural after giving birth?. Thank you ❤️❤️
