So I had a bit of mucusy blood that is pink with a bit of brown just a bit ago. I am 9 weeks. Im sure its all fine. But when do you get to the point where you need to go see a doctor? When it keeps bleeding and cramping? My husband wants me to go but I want to wait to see if anything else will happen

Edit. Heres a pic of what it looked like. Sorry for the black lint from my underwear on the toilet paper
