Period and pregnant? Miscarriage?

i did a pregnancy test on 22nd October came back positive. I’ve done 4 at the drs they also came back positive I have done 3 more home tests between 22nd & 30th October. I had bloods done & they came back positive. I would be around 4/5 weeks but I came on my period last week & still bleeding now I don’t know if I’m having a miscarriage? My dr told me to treat this like a period & to do another test on monday but I’m really scared☹️ anyone else had this?
