Help: Question about monitoring your cervix.

Ashley • Proud wife, mom, bonus mom (step-mom), and physical therapist! Expecting baby #2 February 2018. Loving my hectic life!!
Hey ladies! I'm looking for some help and answers. Glow says I'm entering my fertile window starting today. I have been monitoring my cervix and it still feels firm and closed. I'm getting discouraged because I feel like this means I won't be able to conceive. Any advice or insight would be greatly appreciated. Thanks in advance for the help! ?
