wat causes the cervix to be pushed too far?

The cervix changes position during the month with your cycle.

I've never heard of a doctor NOT being able to find it!
If the Dr. can't find it with a speculum, it might be harder for his little swimmers to find!

Your cervix should be high just like during ovulation, except closed. It will also still feel soft, more like lips. Unless you've been checking your cervix consistently there is almost no way to tell where you are in your cycle through this method. Remember to wash your hands before you check, but other than that, you should have no problems with infection. Just don't get your hopes up that you'll be able to detect pregnancy through your cervical position, especially if you haven't been monitoring it's position already.
