Spotting at 7 weeks

So yesterday my smart self deviced to do some yard work and I think I might have pushed myself a little too much. Now when I wipe there is reddish on the paper not clots or nothing like that and I am cramping a little.  Took a test this morning and still strong positive. Need some advise is this normal? I know you aren't Drs etc just want to hear someone's experience etc
