OK, so these pains. Do they start in the front, or in the back? If they start in the front, they are BH. If they start in the back, they are probably warm up "fer real" contractions. Non-productive signs of early labor (which can continue on for some time). BH shouldn't make you stop for breath (although they can).
The vaginal pain is the baby descending. There is normal cervical pain from the baby pushing and turning, then there is the actual pain of the baby descending (in my experience, two very different things). When was the last time you were at the OB? You should be about due for a cervical examination.
Unfortunately, it sounds like your body is raring to go. I say unfortunately because you could sit like this until 42 weeks when they'll just induce you. Or you could start labor tomorrow. I always hated just waiting. Every twinge, I would think "Is this it?! It has to be!!"
