Anak, I need you to see your OB right away or go to the emergency room ngayong araw pa lang, spotting at 7 weeks with no embryo seen is something na kailangan i-check agad, hindi pwedeng antayan. Please don't worry alone, call your doctor immediately and let them do the proper ultrasound and tests to see what's happening, okay? Your health and baby's health come first, always.
