I’m confused ?

So I got 4 positive pregnancy tests one 10/17/19 it was faint you could see it but it was very faint the next day 10/18/19 I took 2 more one at 4am and one at 8 am they both came back positive before 3 minutes they was faint you can see them a lot better then the day before 5 hours later I started spotting pink I was told by my friend that it was normal on 10/19/19 I was still spotting so I took a test at 5am and there was still a line but lighter then the day before then the spotting turned into full on bleeding so I went to the hospital I took the tests with me when I got there the doctor looked at the tests then looked at me ( without doing any tests or anything) he said your not pregnant because the test line has to be as dark or darker then the control line I looked at him and asked if he sees the line on the tests all 4 of them he says yes I can see them but that don’t mean your pregnant then a different doctor came in and did blood tests and told me I was having a miscarriage I’m so confused
