Sis, yan ay medyo unusual talaga, yung ganyan na pattern ng regla, especially after a long gap and then heavy bleeding, kailangan talaga i-check mo with a doctor para sure, kasi maraming possible reasons (hormonal imbalance, thyroid issues, stress, or something else) at sila lang makakasabi based sa exam and blood work. A few of my mum friends had irregular periods after a while, and discovered it was thyroid or stress-related, so better na ma-rule out lahat ng possibilities para matulog ka ng mahimbing at alam mo exactly kung ano nangyayari sa katawan mo!
