Wanting to be preggers!

This may be TMI, but my first pregnancy came to a complete surprise we not trying at all. Now my child is 2 and we have decided to try again for a second! :)... So this time I am way more into learning about when I'm ovulating and my cycle (why I have this app). One thing I have become super interested in is my cervix and how it helps figure out when your period is coming and how it's different before and during pregnancy! But I am so confused! This is something so foreign to me haha I read all this stuff about high, low, soft, open, hard! I don't know how to tell!! Is this something you would have to be doing for a while to really notice a change?
