Low cervix during fertile window???😣

I’m in my fertile window and on my third day of flashing smiley on opk at the moment but I went for an examination today and the nurse said my cervix is low. Is this normal as I thought it was supposed to be high when your fertile? But it’s low and I’m getting close to ovulation 🀨 should it be high by now or can it change the closer I get to ovulation ? W
