Vaginal pressure/cervix pain 27 weeks


So my husband and I just traveled to see his grandparents. It’s a four hour car ride and I made sure we stopped and I walked around for 15 minutes in most of the towns on the way. But I have had pretty uncomfortable pressure/pain in the lower pelvic area and what I think is my cervix since! I’m a ftm so have no clue what the signs of early labor would be. I’m not crampy but I do have some pain in my stomach when I get up to move from sitting or anything like that. When should I be concerned? Is this normal? I hate that I can’t just go to my OB!
