I had the same bleeding when I thought I was about to start my last period - turns out it was implantation, tho lasted 7 days. Nothing after that for a month.
On Weds I had a scan that showed I was 7 weeks; good heartbeat and size. I've had no pain, no sickness, just sore boobs and bloating.
Noticed brown blood with a touch of rusty maroon when I went to the loo this aft. A/E doc took blood pressure etc but said I'd have to come back for a scan on Monday.
Am sobbing and terrified and can't believe I have too wait three days to find out if I'm miscaerring. Does anyone here have any experience?
