Oo, normal talaga yan, lalo na sa first few months ng pills! A few of us tried different contraceptives and lahat kami nag-adjust ng iba't ibang ways, some had spotting, some skipped a period, some naging super light lang. It usually settles down after 3 months or so, pero kung super worried ka or hindi pa rin regular after that, better to check with your doctor para sure at maybe i-switch mo lang ng brand if needed.
