Cervix Changes

If you checked your cervix while ttc when did you notice it close and move higher ? I'm 6 months postpartum and have checked it here and there and it has felt open everytime. About two weeks ago I had unprotected sex and have been wondering if I could have gotten pregnant. Three days ago I checked my cervix and it felt closed this time. I just checked it today and I can barely feel it at all. I'm going to take a test soon but I'm just wondering if this could mean something. I dont have my period yet so I cant go off of that.

I understand it's not exactly a prediction of pregnancy. Im just wondering if anyone noticed it happen when they got pregnant. It's the first time theres been any difference in my cervix position since I gave birth so I'm curious
