TMI question- cervix position

I'm nearly 15 weeks, and wondering what the position of my cervix should be at this point (worrying that it's too low). I'm seeing my MW in a couple of weeks, and will ask her then, but wondering if anyone could fill me in?

Only ever checked cervix position when TCC...

from what I understand (read it in a book somewhere) your cervix position changes during the pregnancy. When I conceived but before I got my BFP, the first thing I noticed was it went higher and was tightly closed.
Later on it does come back down. As you get closer to your due date it will start to go up and thin out from the pressure of the baby. This is how the doctor of MW knows at 40 weeks if you are getting close or not.
Like the others say, you need to be very careful of infection as an infection can cause a early labour. I would try to relax and trust that your body knows what it needs to do.
Everybody is different though and the position changes so you can't really tell too much by it.
