Dont know what to do?!

So i got a positive test on Thursday but I started bleeding on Sunday morning after being 6 days late I asked the doctor about it she wasn't very helpful didn't want to do bloods just said I was stupid for testing before I was 2 weeks late, anyway the bleeding was light Sunday and barely there on Monday and there's been next to nothing Tuesday and nothing today so I'm really confused! Could I still be pregnant?!
