Hi mommy! Yup, normal yan, the primrose oil can soften and leak out especially pag mainit or kapag gumagalaw ka, kaya maraming mommies nag-insert before bed para mas matagal siya mag-stay. Pero since you're already at 37 weeks and 6 days, mas maganda talaga i-confirm with your OB kung okay pa rin ang primrose for you at proper insertion, basta sigurado na safe at effective for your situation, kasi every pregnancy is different talaga!
