Girl, 9dpo is still super early, kahit may line, it could still be an indent or evap kasi the hormone levels are so faint pa. A few of us tried testing that early after our miscarriages din, and honestly the stress of squinting at lines was more heart-breaking than helpful, so I waited til at least 12-14dpo para mas clear ang result. Best thing would be to retest in a few days gamit urine from the morning, or better yet, ask your OB para ma-confirm with a blood test, that's the most reliable anyway, specially after what you've been through. Sending you baby dust, sis!
