Cervix changed ?!

Today is day cycle 15 of my cycle. I believe this cycle to be 32 days like my last one. Anywho, today I’m experiencing cramping and it’s been off and on since I had sex on Friday and continued. Anywho, I’ve been checking my cervix and today inside feels really tight. I can’t explain it but it’s never that way and upon its right feeling(I mean my vagina was wrapped around my finger, TMI) and I noticed my cervix positioned changed from the day before yesterday. It was in the middle now it’s tucked tightly on the right side is this normal??
