1st Period after CS Delivery

Hi mommies, question lang, when did you have your regular period after giving birth? I'm a breastfeeding momma and 6 months na si baby, until now wala parin akong period. Yung mommy friend ko who gave birth 6 days after me, meron na sya although mixed feeding na sya sa baby nya. I just can't remember kasi if it took me 6 months din bago ako nagkaron sa 1st child ko. Parang ang tagal na kasi. Thanks!
