Hi mama! I haven't taken Duvadilan myself kaya hindi ko ma-share ang personal experience, pero alam ko maraming preggy moms na nag-take nito for contractions, usually okay lang sila with minimal side effects like slight dizziness or palpitations, pero basta short-term lang talaga. Since nasa 37 weeks ka na at first time mom, best talaga mag-check directly with your OB kung may concerns ka sa side effects or kung paano ka nag-feel habang nag-take, kasi every pregnancy is different at siya lang makaka-monitor properly! You're almost there na, mama, kaya mo yan!
