Should I test?

Autumn
Me and my husband have been ttc for 3 years and I'm about ready to give up, but I'm 1 week late on my period, and I haven't had any symptoms of pregnancy. I've been through this before and have gotten my hopes up only for them to be crushed. I don't know if I can handle another let down. Should I just take a test or wait to see if I get my period.
