Please help

So I got AF yesterday after getting faint lines on tests, (could have been indents, I figured they were since I got AF) it was very brown and almost blackish at first. Which is not the norm for me. Now tonight it has picked up and it’s very painful. Feels like a constant pressure on my uterus, and even hurts to sit/stand up. At times worse than others. I feel like I’m constantly bleeding. So I decided to test since I’m crazy and wanted to make sure nothing was wrong. And I got this. I feel like only on some pics I see something, and I’m just so confused. Do these look positive or idents? Should I go to ER or am I just freaking out? Not really sure what to turn to!
