Pregnancy test question

I took a cheap dip stick pregnancy test today and got a VVVVVFL. I also took a first response early result, dipped it in my urine and got a negative result. Both with First morning urine. The day before yesterday- I took one of the cheap ones again (fmu) and also received a vvvvvfl. Are the cheap tests wrong? I got them from eBay in bulk they are high sensitivity.???? Or Is The First response wrong??? My period was supposed to start yesterday but didn't. I also had HORRIBLE I MEAN HORRRRIBLE cramps yesterday.
