Miscarriage likely, feedback appreciated

I'm currently 7 weeks exactly, but probably wont be for much longer. The first photo is from a test I took last week, and the test line is clearly much darker than the control line. I started bleeding about 6pm last night, very dark red, no clots, no cramps. It turned from red to brown within an hour, and I've continued to bleed brown since (about 15 hours). I tested this morning, and the test is noticeably lighter than the one from last week. I assume this is indicative of an upcoming miscarriage, but this is my first pregnancy, and feedback would be appreciated. Thanks.
