Ay, good question ito! So honestly, it depends talaga sa brand at type ng injectable, some women still get their period, some don't, kaya importante mag-consult sa OB mo about what to expect with the specific injection you're planning. A few of us din nag-injectable, at may kaibigan akong completely nawala ang regla niya, pero yung isa naman ay May-light lang, so it really varies per person talaga!
