Okay guys...Help me out!  Could I be pregnant?

My husband and I were married almost a year ago and we have recently started trying for a baby (within the past 2-3 months).  My last "period" was April 8.  I started spotting April 25, about 2 and a half weeks before my next period.  The spotting was mostly light pink, a little brown... lasted 4 days but nothing like a normal "period"...only 1 day was a little heavier that required 2 tampons...but it still was not heavy at all.  I took a pregnancy test that showed up negative yesterday, which should have been the day I started my next period and it was instantly negative... and I still haven't started.

Could I still be pregnant...?  How long should I wait before I take another test...?

Thoughts? 

 

Thanks guys!
