Cramping and spotting at 6 weeks

Robyn
Hey guys I need some advice. I had a miscarriage in March and we recently found out I'm pregnant again. Yesterday arvo I had a few cramps in the afternoon and noticed I had a slight brown tinge of spotting when I went to the toilet. Iv woken up this morning with constant faint cramping. Should I go to the hospital/ being Sunday my dr is not available?
