I've been bleeding on and off for 5 days, had one sharp pain on the first day, I use one pad a day and it's no where filled up. It's usually brown and some times red. I do not have any clots coming out either. Hcg level was 3400 range on day 3, going tomorrow for another reading. Nothing was seen on ultrasound I am 5w 6d today.
