Engagement ring too small?

Lexi

Hi there! I just got engaged (woo!) but I’m worried that the ring is a size too small. I normally wear a 7-7.5 I think, but I don’t wear rings much. This is a 6.5. I can take on and off with a little force and when I push up on the bottom of the ring, there is space between ring and my finger. Just wondering if I should size up or not!
