Genuinely worried

Hannah

So I had Kyleena removed September 29th. Got a period October 2nd-6th. Estimated ovulation was roughly October 14th-16th. It is November 3rd and no period. All I have is some light occasional cramping. No spotting or any other sign. I took the top pregnancy test October 25th (second pic is inverted) and the bottom October 31st (last pic inverted).

Will be testing again November 7th. Any advice?
