Pink tint when wiping after using the restroom?


I’m 26.5 weeks and today i started cramping and having low dull back pain very much like menstrual pain. Went to the bathroom about 30 minutes ago and had a slight peach tint when wiping after peeing. Just went again about 10 minutes ago and it’s more of a pink tint. Waiting to have to go again to check and see if it’s still happening and if so than calling labor and delivery to see what they think I should do...anyone else experience anything?
