Bleeding

Was at the ER today for possible leaking fluid that was normal but when they did my exam I started bleeding bright red blood. They did an ultrasound and they said my baby BOY was perfect! We also found out the gender. But I can't help but still be worried. Blood has slowed and has turned from red to brown. Said blood was from cervix being irritated by a bacterial infection..any advice, 16 weeks 2 days
