Could this be signs of a miscarriage?

My period is late by a week I was having unprotected sex with my baby father and 2 days ago he grabbed my hair and dragged me to floor rest of its a blur I’m not sure if he’s hit my in my stomach or anything or if I was even pregnant but I do know I am traumatised! however my period never starts like this especially with the long stringy blood and the grey tint to it last time I had something like this I had lost a baby but I’m not to sure if I was pregnant this time? I had been having a few stomach pains after it happened but I was assuming it was nothing so tried not to let it bother me but now I’ve started bleeding and there’s different types of red, even with a grey it in and it was kind of gooey.

Would a normal pregnancy test be able to confirm if it’s a miscarriage ?as I know to check if I had one before they used a hcg strip in the doctors to check if I was pregnant and there was a line which had disappeared after about 2 weeks however I don’t want to go to doctors due to covid. Also after I took this picture wiped and pulled my leggings up I looked in the toilet and there was a clot.

I’m pressing charges on him but they’re trying to find him

Update: the bleeding had just got a lot heavier like I have just felt a wholeeee lot drop into my pad that I have one and some slide out🤮
