???!anyone

I'm usually ready bad at keeping track of my period that's why I have this all to keep track of it but my phone got damaged and lost all my data of my period my cycle is for the most part ever 28 days and my period last for 5/6 days it's usually always on time and if late just one day late. So since I had no data of when I had my period or any data like I usually do I had no idea I had been having sex on my fertile days so not my period is 4 days late and idk if it's too early to take a pregnancy test and if I do witch one is the most accurate pregnancy test there's out there?
