My period is about 12 days late. Test result negative,don't know if I tested to early?

My period is regularly on time. I am 28 day cycles and my last period was Dec. 29th. I was suppose to start on the 28th day of my cycle. Jan25th. I am having a few symptoms like clothing feeling tight, gassy, bloated, movements in my stomach like fluttering, and sharp pains in the pelvic that lasted a day or two. Should I wait another week or two and test again.
