I'm feeling discouraged

CD

During my 35 week appointment today I had my swab and pelvic check. Well attempted to have a pelvic check. I was so tight down there that it was so painful just with a finger. She had to stop because I couldn't take it. This has made me think that I won't be able to give birth vaginally. All I want is to give birth naturally (med-free and vaginally) to our baby girl and now I'm so down that I won't be able to. Has anyone been very tense down there through pregnancy and then had a successful vaginal delivery?
