Hay, first time mommy here too so I totally get the worry! Subchorionic hematoma is basically bleeding between the placenta and uterine wall, and honestly marami sa amin mga kaibigan na nakaranas nito, some had light spotting, iba walang symptoms pa lang. Best talaga na makipag-usap sa OB mo about yours specifically kasi depende sa size at location, at para mapakali ka talaga, doctor lang ang makakasabi ng exact situation mo. Sending you strength!
