Cervix Opening Tilted Down Suddenly

Anya

I started checking my cervix last cycle. For 2 months, the opening always faces forward towards my stomach. whether it's high or low or hard or soft, the opening is always forward. For the first time today, when I checked it, the opening was pointed straight down towards my vaginal opening rather than forward. Anyone experience this? Is this normal? I'm due to get my period in 2 days. Is this a period symptom I somehow missed last month?
