period,early pregnancy or miscarriage..

blood trigger warning!!

so i took a pregnancy test on 6/4 had a faint line faint but it was there within the time frame thought maybe it was evap or false so i waited well then i started light bleeding figured okay maybe it was implantation bleeding but yesterday i started bleeding heavy like thick blood clots and some even looked like stringy jelly like tissue and mucus accompanied by cramps i figured okay maybe its a miscarriage so i took another test yesterday and the line was darker then the first test i took days prior.. im so confused what this could be if it was a miscarriage why would my pregnancy test get darker.. i am also on the birth control patch i dont think its period it doesnt feel like it its not blood in my urine when i pee just strings and clots of blood.. and i also have very irregular periods i just want some of yalls ladies opinions i an going to go to doctor monday tho
