Help!

Shelbie

So I'm 4 weeks and 5 days and yesterday when I went to the bathroom when I wiped there was a good amount of brown discharge and it had me really worried, it went on for the whole rest of the day and night with some mild cramping, is this normal at this stage? This morning there has been barely any but it is still there when I wipe, this is my first pregnancy so I'm completely in the dark and freaking out a little. Some help would be greatly appreciated
