I had spotting from wk 5 -6 with ds.
This pregnancy (#3) I had bleeding from wk 6 - 9. I was convinced I was m/c, because I`d had a loss last year and the bleeding was heavier than with Ds. Also it went on for ages and I felt quite unwell. Eventually it turned very dark brown/black red and then stopped. Never found out what caused the bleeding, but here I am a month away from having that baby I thought I`d lost.
