Ay sis, totally normal yan sa first few months ng micropill kasi ang body mo pa lang nag-aadjust sa hormones! A few of us started micropill din and may ganyang irregular bleeding muna for 2-3 cycles before it settled, yung one friend ko pa nag-bleed twice in one month din like you, so don't worry. The dark red bleeding and lighter flow is usually okay, pero since it's your first time on it, best pa rin na mag-follow up with your OB para marinig mo from them kung normal lang talaga para sa peace of mind mo, at para ma-confirm din na consistent ka sa pagtake ng pills every day exactly. Keep taking it on schedule at give your body a couple more months to regulate!
