Do I raise my hopes or no

So my husband and I have been ttc. My mom and him are so sure that I am pregnant but I keep telling them that I don't want my hopes to get super high because I don't want all the hurt and seeing the pain in his face if we aren't. Af is late by 7 days, the smell of chocolate and tacos make me want to throw up, both my hips have been hurting, and I'm overheating way more often than I have before. Do I let my hopes get raised or do I cautiously wait?
