Are these positive or am I crazy?

I’m currently 11dpo and on cycle day 35. My period should be due in 4 days according to my app. I ovulated late this cycle and did a test last night as I am late according to a different app I have. Do these look positive or like indents? I took a clear blue digital but that said not pregnant so I’m very confused. The only symptoms I have are cramping and fatigue. I had a miscarriage in February last year and an ectopic in June which ruptured a fallopian so am I very worried about either happening again. Could do with another set of eyes and some opinions. (The top 4 tests were taken last night and the bottom 2 were taken this morning)
