Uyy, this is something you really need to check with your OB agad, ha, light brown spotting with an IUD can mean different things, and you deserve peace of mind. Please don't wait on this one, mama. A few of us moms in my circle have had IUD adjustments, and honestly, ang best advice talaga is to get it checked properly kasi alam namin kung gaano kaba-anxious yan. Your doctor can see kung normal lang siya o kailangan ng adjustment, go na, okay?
