Ay mama, kaya mo yan! Nakaka-stress talaga ang spotting pero ang good news is baby's heartbeat is strong and she's in the right position na, so your OB is monitoring everything closely, that's what matters most. A few of us sa barkada had similar cases near the end ng pregnancy and minsan yan talaga nangyayari, especially pag may placenta issues or cervical irritation, kaya good na you're taking the meds prescribed mo and going every 2 weeks. Just keep an eye sa spotting, and if it becomes heavier or you have severe cramping, don't hesitate to call your OB agad ha, pero from what you're saying, sounds like you and baby are okay. Hang in there, almost there na kayo!
