Is it normal na mag bleed at 18 weeks like maliit lg naman na bleed po

contact your OB for sure bigyan kang pampakapit, same scenario with me 1st time may bleeding at 18weeks sobrang konti pero yung kaba ko wagas kaya tinawagan ko agad yung OB🙏🏼not normal ang mga bleeding brown,red,pink basta dugo🙏🏼🙏🏼🙏🏼
