Hi mama! A tiny bit ng spotting after transvaginal ultrasound is usually okay, lalo na if it's very light lang, pero since ito ang first time mo and gusto mong sure, mas better na i-mention mo agad sa OB mo next time or kahit tawag na lang ngayon para peace of mind, a few of us moms had the same worry and ang doctors namin all said it's normal pero mas comfortable kami after confirming talaga. Mag-rest ka lang for now at monitor if it gets heavier or may other symptoms na concerning!
