Miscarriage likely, feedback appreciated

Currently 7 weeks, but probably not for much longer. The first photo is a test from last week, test line clearly darker than the control. I started bleeding last night, very dark red, no clots, no cramps. It turned from red into brown within an hour, and I've continued to spot 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.
