took test too soon??

Alana
So lately I've been experiencing  several pregnancy symptoms. My BF and I have been trying for a baby. I've been experiencing nausea fatigue increase in appetite heartburn (which i never had in my life except for when I was pregnant with my son) weird cravings etc. I use the flo <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> which tends to not be accurate but it says I'm supposed to start my period in 3 days. I just took a test and it came out negative so I'm really disappointed. Did I maybe take it too soon? Do I have any hope of being pregnant???
