Mama, please see your OB as soon as possible para ma-check properly, this really needs a doctor's assessment kasi alam mo, cervical changes in early pregnancy need professional monitoring.
A few of us mums have gone through worrying situations during pregnancy din, at ang best talaga na ma-guide ng doctor mo step-by-step, kasi bawat case ay different. Sending you strength, and please don't delay ang check-up ha? Your baby needs you to get proper care.
