Mama, this is really important, please see your doctor or go to a clinic as soon as possible, okay? Three months after that kind of procedure with a still-positive test needs proper medical check-up to make sure everything is okay with you. Hindi dapat maghintay pa, lalo na walang period pa rin.
I know this is stressful, but only a doctor can figure out what's happening, whether it's leftover hormones, something else, or if you need care. Please don't delay this one, sis. Your health comes first.
