Implantation Bleeding??

Hello Mommies! Good Day! Sana po may makatulong sakin. Hindi ko alam kung spotting/Implantation Bleeding ba itong nararanasan ko. It started June 17 and up to now meron parin akong spotting. Bale 10 days na ngayon. Ang Last menstration ko ay nung May 30, supposedly ang next menstration ko ay magstart June 25 onwards. Nag try ako magPT kahapon. Negative. Posibleng Dahilan ba nito ay may halong dugo kaya ung urine ko? Kaya siguro lumabas na Negative? I really don't know. Sana may makatulong po. Thank you in Advance!
