Hi! Yan talaga minsan ang side effect ng lady pills lalo na pag baguhan ka pa lang, ang period mo pwedeng maging super light or maikli, kaya normal lang yan. A few of us moms experienced the same thing nung nag-switch kami ng pills, pero kung concerned ka talaga o if it continues to change significantly, better check with your OB to make sure the brand you're taking is compatible sa body mo, kasi bawat tao e different talaga. Keep monitoring mo lang for now and see kung stable na after a few more months.
