34th week

Ss
Hi friends i am 33 weeks and  4 days today and for the first time am feeling the cramps or tightening which is light but evident and goes off in a few minutes. It didn't hurt but felt like menstrual cramps. I have not felt Braxton hicks contractions  till now. Is this it. Only today i felt a little pressure in my pelvic region. I feel good in general but was a tired today. When did you all go through this phase .  Just want to know. I have my appointment in  couple of days and would discuss with my obgyn :) thank
