Is it normal to have bleeding when 6th week pregnant?

Hi, I had spotting (pink brown discharge) then it grew more and I went to KKH urgent O&G for check up. It's 24hrs at KKH women's clinic B1. If it's your first visit doctor will do a urine test to confirm your pregnancy follow by ultrasound to check your baby. Usually 5-6 weeks is still quite small to see. Depending on the bleeding, doctor will prescribe hormonal/folic pills to help "maintain" the pregnancy better.
