Light bleeding but no cramps/pain

Hina

It started last friday after my internal ultrasound. Immediately after i noticed very light pink discharge when i wiped. Since last night the blood is darker but still very light. I have been wearing a pad but theres hardly anything on the pad when i go to the toilet. It is only when i wipe that the blood is visible.

I am really worried because my scan only showed a sac and i was supposed to be 8+3. I have to go back tomorrow for another scan. With my previous 4 miscarriages i had intense cramps and bleeding so i am really confused.
