Confused ....

So the hospital believe I had a miscarriage last week, with very low levels off 49. They said that my hormones should drop very quickly. Well today I’ve just done a test to see if it was negative yet and it’s blazing positive nearly a dye stealer. The darkest test I received even before ‘miscarriage’. Really confused off what is happening. Has this happen to anyone else??

Also I shall note I done a test yesterday and it was positive but not ask dark as the one today ?
