Help me understand my cycle

My cycle have been the following dates (picture in comments). Is it safe to say that my period is 26 days cycle? If so, I need help understanding the symptoms that I’ve been having recently which don’t feel like PMS. My GYN says it sounds like there’s a probability of pregnancy. Today is CD18 and AF is due in 9 days. I am having these weird cramps that feel like my period is coming but not necessarily like period cramps. I also have these twinges that come and go but they’re sharp close to my hip and lower back. Everything tastes like metal and sleep has been my favorite hobby.
