Anak, please see your OB or go to the clinic ASAP to check on this, any changes sa abdominal pain in pregnancy, especially after consistent pain like you had, need to be checked properly by a doctor. Hindi kami dapat mag-guess dito kasi importante ang baby mo. Once you've seen your doctor and everything's okay naman, maraming isa sa circle ko na nag-experience ng cramping sa early pregnancy, tapos nag-settle lang. But the shift from constant pain to walang sakit suddenly, kailangan talaga ng professional check-up para sure, ha? Praying it's all good with you and baby!
