Ladies I need advice please

Lis
So I was/am going on 6 days late (which is never normal for me) so I went to the doctor Friday and there test said negative but they seem to think I am, he said that if I gat a positive to call and if I keep getting negatives in a week to call and schedule blood work to take it easy and be careful if I start having horrible pains, or bleeding bad go to the er well now I woke up to bleeding it's not super light, but not super dark it's not heavy but it's definitely there, and I'm not having much cramps or much pain with periods like I normally have, what are your opinions? Could I still be pregnant? Please please please comment what you think & thank you so much
