Hi I Just Discovered About A Week Ago That I

Hi I just discovered about a week ago that I am pregnant. My period was 6 days late so I decided to take a test and it came back positive . According to the date of my last period I am about 5 weeks pregnant. Yesterday I started noticing some light brown discharge when wiping . I was wondering is that something that I should be worried about or is that normal? I am hoping it's not a sign of a miscarriage.
