The blood was probably from your anus, which a small amount is normal from straining it rips a little coming out. I'd say your completly fine
This is common with constipation or if youre butt is raw. Could be hemmorhoids or anal fissure(tear). As long as your not bleeding from your vagina or with your urine I wouldn't worry too much. If it becomes painful or alot of blood which comes out with stool then you need to see your Dr.
It was probably from anus your where probably straining which happened to me when I wasn't pregnant its possible for your anus to bleed while doing number 2
