I have a question

Hi, everyone! I haven't posted in this thread before. Glow always ask if I checked my cervical position.. My question is how do you check that? How can you tell if it's open/closed high/low soft/hard all that stuff? We are trying for baby #2 so I want to do everything glow asks of me so glow is more accurate but I'm very modest, not closed minded or anything but I've never "explored" my body so I'm not even real sure where to look/feel or what I'm actually feeling for. Can anyone explain a little.
