Ay, preterm birth worry, valid talaga ito! I haven't personally experienced it, pero a few of my mum friends na may history ng preterm did everything from strict bedrest to frequent monitoring with their OBs, at ang consistent advice talaga ay close follow-up appointments, managing stress, and staying hydrated talaga. Honestly though, best ka magtanong directly sa OB mo about your specific situation kasi bawat case different, kung may family history ka or previous preterm experience, they'll give you the best plan para ma-prevent. Ingat always, mama!
