Please Help ease my mind ladies..

Hello just lookin for a little support here. About 11 months ago I went through an ectopic pregnancy, then just found out I'm pregnant I am now 5 weeks an 4 days pregnant.. 4 days ago I started spotting brown, then like a dark wine color an then brown again, about 2 days ago it got a little redder in color only when I wipe an a few drops on a panty liner mild cramps not too bad... An it's more dark today it's been almost 6 days that I've been dealing with this, Anyone experience this an had an ok pregnancy? I have an ultra sound next wed, an got my blood taken yesterday to check levels but I just can't get my mind off the stress..
