Hi mama, ito talaga ay something you should bring up with your OB kasi ang hormonal pills ay dapat consistent ang effect, at kung biglang tumigil ang period mo even with negative PT, kailangan i-check kung okay lang lahat internally! Don't worry though, many moms experience irregular bleeding when they first start contraceptives, kaya hindi ka nag-iisa dito. Best to get a proper check-up para ma-rule out any concerns and makita kung ang Daphne or Excluton pa ba ang best fit para sa'yo, or kailangan ng adjustment. You're doing the right thing by being observant about your body, mommy, that's already great parenting energy!
