Uy mama, I know scary ito, but please check with your OB agad, kahit light lang, better to get it checked out to make sure everything's okay with baby. Blood in urine during pregnancy needs proper assessment from your doctor, so don't wait ha. A few of my mum friends din nag-experience ng similar concerns early on, and ang reassurance from their doctors really helped them relax. You're doing the right thing by asking, but your OB needs to see you, go tomorrow if you can, okay? Sending love your way!
