Don't know what to do.

Hailee • Married June 2014. TTC since Aug. Lost baby #1 at 4 weeks on New Years of 2015.
Cycle day 29 and DPO 12. I'm almost a week late. I took a test last weds two days before AF was suppose to be here and got a negative. My temp has been higher then normal and around the same temp for the past week. I'm also having some symtoms.  What does this mean? Could I be pregnant or just an off month?
