Cervical Check Help!

I just did my first cervical check on myself ever. It was very high, felt like the tip of my nose, and I could feel a slight opening, but I'm not sure if that means that it was opened or closed. I'm on CD 19 with PCOS and I'm still breast feeding  and I've been having 2 lines on ovulation tests going back and forth between full on positive and nearly positive for 8 days now! Help!!
