when should I test?

Emily
My last full period was January 2nd-6th and then I had a 3 day lighter period January 26th-28th. I have unprotected sex because my boyfriend and I are trying for a baby. I took a pregnancy test February 22nd and it was negative. 
I have horrible acne on my face and my chest and back, my stomach is extremely bloated, I'm exhausted all the time, I have small cramps in my lower stomach, and awful heartburn all day long and it's worse when I first wake up. My boobs aren't sore or anything. 
The last day I had sex was February 19th. No period since the 3 day one in January. 
Should I test again?
