Faint lines then nothing and still no period


Hi everyone I posted a test here on Saturday asking if anyone else could see the very faint positive on the first response test and everyone that commented could see it. I was due period on Sunday the next day and tested again with a clear blue test and thought I could see another faint positive. This morning I’ve tested again with a digital and said not pregnant. Has anyone had this and still been pregnant? I’m losing hope now. I’ll post the pics that I thought were positive on Saturday and Sunday x
