Confused

Nicola
Help ladies! Last Sunday I went to the hospital as I was bleeding (was five weeks) they did an internal and said my cervix was closed so no sign of miscarriage.
I had an early scan and they said there was no sign of the pregnancy so said I probably miscarried, but my hormone levels were increasing still.
This week I've still got my pregnancy sypntoms and just decided to take a pregnancy test to see if it was negative and it's still positive?! Could it of been to early to see anything?
