I think I've had a miscarriage at 3 weeks, 4 days (cramps, blood clots, stringy, bled for 8 hours). Had got positive home tests (took 4 over 3 days) at 20 days. I'm nervous about taking another home test to check - I don't want to deal with getting a false positive, I'd rather know if it's over, but I'm also desperate to know as soon as possible. How early would you advise taking a test? - It's now 13 days since this happened - will all the blood hormone be likely to have gone given mc so early?
