Worried

Today i am 7 weeks and 5 days. This morning i went to the restroom, wiped, and there was brown discharge. It went away, then hubby and i had sexy time , then when i went to urinate , there was blood. Not enough to be alamring but still the fact there was blood alarmed me... Is this normal?... my appointment for my baby isnt for another 2 weeks and i dont want to go for a false alarm if this is normal. Maybe i teared something ? Idk..
