first response and clear blue digital

so basically I have already two children, my second child I got caught pregnant on the implant. I currently have the implant again because it helps with my periods because I suffer really bad with them. Two months ago I found out that I had gotten pregnant again on the implant but lost it. I’ve currently taken two first response pregnancy test and I don’t know what to think off them? but taken a clue blue and says not pregnant just wondering if anyone could help
