Minta pendapat

Hi semua. I nak tanya, pagi td i ada buat swab test utk GBS then malam td i pergi toilet then i notice mcm ada blood stain sikit di pantyliner. Tp bukan di tengah2. Skrg i confuse from where the blood stain is. Adakah sbb dr i buat swab test tu or luka after shave. Tp i rasa mcm xde luka. Currently im at 35w4d. Baby so far gerak semua ok. And i monitor as of now tiada lg blood stain lain. Sorry gambar agak disgust
