5 weeks & 5 days

I started off with spotting but for the past few days I've been bleeding. It's not heavy enough to fill a pad. I was told it's normal and not to worry about it unless it seeps thru the pad or there is clots. There has been no clots. It's like I've got my period but a light one. 
Has anyone else had bleeding thru their pregnancy? I'm worried I've had a miscarriage 😞
