Hay naku, anak, this is something you really need to talk to your OB or go to a clinic about ASAP, hindi ito dapat waiting game, kaya please get checked this week if you can, okay? I know it's scary, but only a doctor can properly check kung may pregnancy and how far along, lalo na may expired injectable involved. A few of us moms have been in similar worried situations, and palagi naming sinasabi sa isa't isa na it's always better to know early. Please don't stress too much yet, go get that blood test or ultrasound so you know what's really happening. You've got this, and you're not alone.
