Bleeding- no explanation ???

Taylor • soon to be mommy to rowen kingsley ☺️✨

I’m 12 weeks and a FTM. I started bleeding bright blood a couple days a go with no cramps. I️ went in and they said everything looked perfect and the baby looked great and my blood work came back and said I’m even having a boy who is low risk for everything. I’m super excited, but I️ keep bleeding and it’s freaking me out... has this happened to any else and still had a successful pregnancy??
