Faint line

Chelsea • Happily married. Have 2 amazing sons and ttc baby #3.
I took a test today and a really faint line appeared within 3 minutes. I'm on cycle day 27 of 33. Supposed to start AF next Friday. I'm really cramping right now and been nauseous all week.. Do you ladies this this is it? I'm second guessing the test since I'm so early..
