Pregnant??

So my period usually happens around the 18th of the month. Still no period! I took a test that read negative. According to the eve app I've got two more days to go til my period. I spotted at the very end of May,  I've  never had a problem before so I'm hoping it's just hormones! I'm cramping a lot today, so hopefully it will just start. I take the pill and have never missed. Thoughts? Thank you!!
