Easy at home tests

I bought them because they were super cheap for how many you got in a package, so that's pretty cool. But has anybody had any issues with them? I am now on CD 44. I do have issues with irregular periods but nothing this bad. I think I ovulated late in my cycle (Glow predicted the 24th, I think it was actually the 2nd) and AF was predicted to be here on the 9th. It's now the 19th and nothing. But I've also had nothing but BFN with the Easy@home tests. I had some mild cramping on the 12th and breast tenderness. The cramping has since stopped, it was only that one day, but my breast are still tender. I took two Easy@home tests with fmu this morning and nothing. Sorry for the long post I'm just scared to get my hopes up. Thanks in advance!

*UPDATE* So besides my breasts being ridiculously tender, zero of my typical pms signs, and the fact that everything is making me cry (for example the Big Bang Theory, are you kidding me lol) I am still getting BFN. Even on FRER tests. I guess mother nature just wanted to be especially cruel for Christmas.
