Faint line??

Someone please answer I feel crazy. I took my first test and I saw a VERY faint line. It was Publix brand so I thought maybe it’s just the test?? Took another test and only peed a couple drops on it because I KNEW it wouldn’t be enough to register and that second test was completely white no cross just one blue line. First one very very faint, 8 days till my period. Had sex when my app told me I was ovulating that week and experienced spotting and light cramping for a few days. Not sure what’s going on.
