Will a pregnancy test determine if I just had a miscarriage?

[EmilyRose90]

The night before last I found vaginal tissue discharge in my knickers. The best way I can describe it is that it is about 6cm and looks like raw bloody chicken breast (I am so sorry for the graphic description).

Obviously I am really shocked and worried about this as have never experienced anything like it. My first thought was it could be a miscarriage although I am really careful when it comes to safe sex and I am on the pill.

Despite this I got a pregnancy test today as I saw online it was still read positive even after a miscarriage but mine came back negative. Does this mean it wasn't a mscaarriage after all? I took the test about 32 hours after the discharge occurred.

Any help or advice is greatly appreciated.

It seems likely that a pregnancy test would pick up a miscarriage that close to the event, unless the embryo had experienced demise a while ago and only just let go from the uterine wall now.  Did you have a normal period this last month?  If no hCG is being produced, you'll get a negative on a test.  

That said, it seems as though there should still be some living placental tissue for at least a while.  Test again with concentrated first-morning urine, to be sure.

You could also google "uterine cast" and see if that resembles what you saw.  If you saved the tissue, you could contact your doctor and ask him to put in some orders and you could take it to the lab to be sure.
