It was most likely a period and not a
miscarriage, if it was a
miscarriage, you might get a faint positive on a HPT, so you can take a pregnancy test just to see if you're even getting a faint positive, but it was most likely a period. As for the discharge, if you were early on it's unlikely you'd be leaking anything, most women, if they do leak, don't leak colostrum until late third trimester.
