False positive?

I took a FRER test on Saturday morning (the 2nd) with a what looked like very faint positive. I decided to test again this morning 2 days later and it seems the line is more faint or maybe even not there. Could I just be testing super early? My period is 8 days away.. I hope my test was positive, does second one still look like it has a faint line? opinions?

First test

Second test
