This is my second month ttc and I've only been using the opks. I can't remember to temp everyday and my ewcm is unreliable cause of sex it's hard to tell. But I started checking my cervix this month too and it changes from low to high, hard to soft, etc, but it always feels a bit open. Is this normal and how do you tell the difference if it's more open during O? I did have one child 15mo ago vaginally.
