Anak, please go to the ER or call your OB right away if the bleeding gets heavier or if you feel dizzy, okay? Hindi dapat maghintay pa sa Wednesday ultrasound if you're worried ngayon, better safe than sorry.
I know it's scary, pero the fact na walang pain at na-prescribe na kayo ng doctor is a good sign. A few of us moms have experienced spotting during pregnancy din, kaya hindi ka nag-iisa, pero bawat case talaga ay different, and your OB needs to assess properly. Just keep close eye sa amount of bleeding and watch for any changes.
For now, rest lang and follow what your doctor said. Huwag mag-alala ng sobra, pero please don't wait if something feels wrong, better you go in and get reassurance na okay lang kaysa mag-stress kayo both. You've got this, mama.
