Oh no, I'm sorry you've had some spotting. Fingers crossed that's all it is.
I had dark brown spotting around week 6 with DS, was just when I wiped & just a few times over the course of a few days. With my mc it was pink & watery, then got heavier quite quickly.
If you've had no cramps & it's just a little I'm sure all is well, but definitely contact someone- mw, dr or epu, see if they can get you an early scan to see what's going on.
Fingers crossed for you xxx
