Daisy, I believe cervical position is a pretty unreliable sign for pregnancy. And to be honest, I would keep your fingers out now, to keep your risks of infection to a minimum!!
This site says it rises up at different times in different women (go to the bottom bit when it talks about pregnancy, after all the ov bit), so don't worry about your cervix when everything else is pointing to the positive:
