Need an outside opinion!

I am currently cd14 and am midway through ovulation. I've been having some mild cramping for the past couple of days which have been right in sync with my ovulating. I'm trying to tell my self it's just ovulation pain, but I have never experienced this before. My husband and I are ttc month 4, after a preterm labor at 23 weeks in Octobor. Could this be an early sign of pregnancy, or have I just totally gone crazy! Advice please!
