All of these positive?

Ashlee

Okay, so the top test is from last Tuesday. I figured I ovulated then. Then, yesterday I took a test and it was dark as well and the last picture is from this morning. The only reason I tested again last night and this morning is because for the past couple of days I’ve been a little crampy, bloated and my back has been hurting. Are all of these positive? I’ve been getting positives for the past 12 days so I have no idea when exactly I ovulated and I’m super frustrated. These pictures are my darkest ones though.
