So confused..possible tmi

So the first picture is from Friday the 24th and the second if from today the 26th. Thursday it shows a very tiny Lh spike, I know it's not positive, and a maybe line or indent on the preg test. Saturday I started spotting with cramps and whatnot. Today, being sunday, the spotting continued but I also started passing very very tiny clots, a lot of them. I know it seems like af, but I doesn't feel or look like my normal af. I'm not suppose to start until aug. 4th....I have no clue what's going on, I normally never spot at all. Anyone have an idea?
