Ay, mixed feeding ka na kaya mas flexible ka! A few of us tried Combined Oral Contraceptives (COC) like Lady, Trust, Marvelon, or Althea, pwede na yan 6 weeks after delivery, kaya if you're past that na, you're good to start. The thing is, may slight effect ito sa milk supply pero since may formula ka naman for baby, hindi siya big deal like it would be for purely breastfeeding moms. Some mums swear by Lady or Althea kasi affordable and reliable, pero honestly maraming options, mag-try lang ng ano ang okay sa body mo. Best pang talaga is to run through the options with your OB or family planning doc para ma-confirm kung aling brand at timing ang best for your situation specifically!
