Bleeding at 21 weeks

This is my first pregnancy, and I went to work as not

al today didn’t do anything out of the usual it started off good.

But then I went to the bathroom and when I wiped I saw blood and there was blood in the toilet. I instantly left work and went to the hospital thankfully everything they checked was good baby is good heartbeats at 140bpm.

But now I’m just feeling anxious and crying a lot because wow was that scary. The doc gave me a list of red flags to look out for but he didn’t seem worried at all which is good.

Has this happened to anyone else?
