Oo, totally normal yan, mama! The leaking happens kasi ang primrose oil is oil-based, so after a couple hours it naturally flows out, hindi siya masisigurado na all of it stays put, lalo na if you're moving around throughout the day, kaya don't worry na nasayang mo it, the important part is naka-absorb na ng cervix yung kailangan during those first hours. A few of us tried primrose insert din, at yan talaga ang nangyari sa amin, so I'd say you're on the right track, just keep doing it as advised by your OB, and ang leaking is definitely not a sign na something's wrong. If you want to minimize ang leak though, try inserting it right before bed para mas long contact time with zero movement, pero either way it's okay lang talaga!
