I had unprotected sex eight days ago.. My period 6 days early it came very light stopped for a few hours started again and stopped then came again and been very light with no cramps and I see tissue when I pee,its deff not a normal period.. I'm sleeping most of my day away I'm craving weird food. I took 3 clear blue pregnant test two came of not pregnant the third one shut off on me.. Is it too early to find out?
