Could I be pregnant? Is this the month?

Lauren
Hi everyone! I've been TTC for 1 year now and I was due for my period Jan 26th. Sunday Jan 25th I took a test and it was a BFN but I've been burping like crazy lately and feeling a little bit of pressure/cramping only on my left side. It's the weirdest thing. Could this finally be the month? My DH thinks I had a dud test. Do you think that's possible and I could be pregnant? When should I test again? I'm going crazy over here and getting in my own head thinking I'm pregnant so I dont know what to think anymore.  Any suggestions are greatly appreciated!
