Confused

Hi I'm 33 years old and last week I did a pregnancy test it came bk positive with a faint line so I did another and it was the same my partner and I were happy but I took another 3 tests 2 days after to make sure 2 was positive with faint lines and 1 negative x so a week later I started bleeding thinking I was having a miscarriage as by this time I was a week late on my period if went to the hospital as I was having no bad pains, the doc did a text and it was negative she seems to think I've come on with no scan or anything what should I do as it's the 4th day of bleeding but it's slowing down now just very confused
