early miscarriage - what happens?

[SilverSixpence]

asking on behalf of my SIL, she had a positive pg test last weekend then ended up in hospital when she felt dizzy after a dentist appointment. she had a negative test there, but they did a blood test to check and rang to tell her it was positive. She started bleeding on tues and it hasnt stopped. Her GP didnt refer her for a scan or do another blood test, just told her to do a repeat pg test on friday?? is this normal, i would have thought it was likely to still be positive until the hormones are out of her system, and surely a scan would be needed anyway to confirm? please advise thanks. she thinks she was about six weeks, and it is her second mc so i really feel for her, especially as me and another SIL have just had babies

I've had 3 and yes, they should def scan o make sure that it is a m/c and if so that all has passed.
You can get a positive result for about 2 weeks after until the hormone levels drop.
The hormone in the blood increases with each day, so they can work out roughly how pregnant she is/was.
I'd advise her to go back to gp. But now they get charged for referrals to hospital they must just be trying to cut corners.

For this early you don't always get a scan - as long as tests come back -ve all should be OK as long as cycle settles down etc. Or that's what I've been told anyway.
