Ay, ganyan talaga usually ang first few months ng depo, sis, ang body mo kasi gumagastos pa lang sa hormone adjustment, kaya ang bleeding ay irregular or mahabang regla like yours! A few of us from our mom group nag-complain din ng ganito when we first started, tapos after 2-3 months naging normal na or wala na talaga. But since this is your first time and you're worried, it's best to check in with your OB kung tuloy-tuloy pa rin ito or kung sobra na ang bleeding, para peace of mind mo lang at makita if kailangan mag-adjust ng contraception. Don't worry too much, marami sa atin nakaexperience na nito!
