Going on my very iffy dates, I'm about 7 - 10 weeks into an unplanned but very wanted pregnancy. I just discovered a smudge of brownish blood in my knickers. I have no cramps and feel fine. It seems to have stopped but I'm terrified something bad has happened. I've had two problem-free pregnancies and nothing like this has happened before. Does anyone please have any advice on what it could be and what I should do?
