pregnancy

So me and my husband have been trying for about 6 months to have a baby. My period is always on time now it's a week late but my boobs are sore that's it, no cramping nothing. When should I take a test. The only reason I haven't yet cause I don't want bad news that I'm not :( ladies please help me. I know I can google it but it's all different answers. I feel like I'm getting my hopes up and when I finally take one it will be negative and I'll start my period. What y'all think
