Advice help!!

At my job I’m walking the whole time. I barely sit. Last night I got home around 2 in the morning. And when I went to use the bathroom I was spotting really light pink it pretty much gone but sometimes when I wipe it’s like a clear pink. I called my doctor and she said it seems normal because I’m 6 weeks pregnant. I don’t feel cramps or anything so I’m doing pelvic rest. Has anyone experienced something like this. And I’ll feel like a slight mild cramp but nothing bad. Is this normal?
