I don't know what's going on

Ok I missed my period on the 3rd so I took a test there was the absolute faintest line so I waited and took another on the 5th and got a darker line so I told my husband then started bleeding on the 6th but still had sore boobs.... I bled all day yesterday but didn't even go through a single pad it was the lightest bleed I have had for a while... fast forward to today I took another test with first urine of the day and got another positive but I'm still bleeding,

am I crazy is it implantation bleeding I don't want to call a doctor and either be told that I miscarried or I'm crazy what is going on!!!!
