Oh, and about the bleeding, it's different for eveyone and for every miscarriage. With my first one, I think I bled and/or spotted for 6 weeks, but with my 2nd and 3rd miscarriage, I bled for about a week.
I'm really sorry, but it does sound like a miscarriage. And about the test, if it's negative then you should not read it after 10 minutes bc they can turn positive and give you a false positive result. That happened to me with a first response a few cycles back. Another thing too, is that even when you miscarry it takes some time for the hcg level to go back to 0, so you can get positive results even after you miscarry. With my last miscarriage, I had a positive pregnancy test for almost 2 weeks after I miscarried.
Again, I'm really sorry.
