Saw more blood this Morning

Chelsey • Due 12/9/19 , Born Nov.29

I went to the er Friday night alarmed because I saw blood & they said the baby had a heart rate of 163 but today I as I just urinated I saw more blood no clots and was just brown . I instantly got back in bed , but I am praying and crying that I’m not miscarrying again as I did in January that everything is okay and my baby is sticking with me I’m going to my ob as soon as they open in the morning I’m 15w+6 has anyone else experienced this ?
