Does this sound like we could be pregnant!? PLEASE HELP 10PTS?

My period is every 7-8 weeks, my last period was June 7th. My husband and I have been having unprotected. 3 weeks ago I went to the gyno because I was experiencing cramping (not normal) - mostly on my right side. Gyno said everything looked perfect - she said it could be early pregnancy. 2 weeks ago, I noticed brown/pinkish discharge so I took a test - it was negative. Now, I am experiencing mild nausea, exhaustion, bloating, mild cramp twinges in abdomen, lots of clear discharge, and sore (tmi)...Most recently its been nausea, hungry alot, and bad dizziness. I wanted to know if i took the test too early 2 weeks ago, if It sounds like pregnancy symptoms, and if i should test ago? I am confused because i have never been pregnant before. Please share you advice and stories.. THANK YOU!
